The entire universe is blanketed in radiation referred to as the Cosmic Microwave Background Radiation, thought to be left over from the Big Bang. If the whole universe is covered in radiation, why is it NOT visible to people on Earth?

Radiation consists of a wide range of wavelengths, and humans cannot see most wavelengths of light.

There is too much pollution in Earth's atmosphere, so no radiation is visible.

No type of radiation can pass through objects, so the celestial bodies block the radiation from Earth.

The radiation is only visible from space, because Earth's atmosphere blocks radiation.

How do human eyes see color?

Each color is light of a separate wavelength, and eyes respond to each wavelength differently.

All electromagnetic waves hit the eyes at the same wavelength, but eyes respond to each type of wave differently.

All colors are the same wavelength of light but change as they reflect off different objects into the eyes.

Each type of electromagnetic wave hits the eyes at a different angle, appearing as colors.

What is true about most of the wavelengths found in the electromagnetic spectrum?

They are invisible to the human eye.

They are found in the range of visible light.

They are able to produce a rainbow when sent through a prism.

In Mr. Hall's class, Amy was learning about light. Mr. Hall showed a white light traveling through a prism and emerging as a rainbow. He explained that all the colors traveling together at he same speed are seen as white light. The reason they are separated as they pass through the prism is because each color has a different wavelength and is bent differently as a result. Which of the following states the correct order of colors of light from the longest wavelength to the shortest?

red, orange, yellow, green, blue, indigo, violet

violet, indigo, blue, green, yellow, orange, red

green, blue, indigo, violet, red, orange, yellow

yellow, orange, red, violet, indigo, blue, green

Carla's favorite ball is bright blue when it is outside in the direct sunlight. Inside, the ball appears to be almost green. Why does Carla's ball seem to change colors?

Color is determined by the wavelength of light reflected or absorbed by the object, and the light changes when Carla goes inside.

Color is determined by the type of infrared electromagnetic waves hitting the object, and going inside blocks Carla's ball from some types of infrared radiation.

Color is determined by the size of an object, and Carla's ball lost air while being played with, so it was smaller when she went inside.

Color is determined by the temperature of an object, and the temperature changes when Carla goes inside out of the sunlight.

What is true about visible light?

Visible light waves are the only electromagnetic waves that we can see.

Visible light is created only when an object becomes hot.

Visible light has a longer wavelength than infrared radiation.

Infrared waves are longer than x-rays.

Microwaves are shorter than visible light waves.

Gamma rays are longer than ultraviolet rays.

Radio waves are shorter than gamma rays.

The picture shows a duck swimming in a pond. Why does the duck appear to be floating above its twin?

The water in the pond reflects light from the Sun, making a mirror image.

The molecules in the atmosphere refract the light, splitting it into two images.

The picture shows a duck that appears to have its body detached when viewed underwater. Why does the duck's body look detached?

because the pond is a different material than the air, and sunlight gets refracted as it travels in and out of the water

because the bottom of the pond scatters the light, making the duck's body underwater appear different than the rest of the duck

because the atmosphere absorbs the sunlight, so it reaches the ducks body underwater slower than the rest of the duck

because the duck reflects the light toward its abdomen, making it look different than the rest of the duck

The picture shows three light rays from the Sun that traveled toward Earth. What happened to light ray Z?

It was absorbed by the ground, which conducted it into the atmosphere and increased surface temperatures.

It was reflected by the atmosphere at the same angle it hit, going straight back toward the Sun.

It was refracted by the higher density ground, heading back into the sky where it made a rainbow.

It was scattered into the ground, increasing the energy in the plates which caused an earthquake.

The picture shows a diagram of light rays as they travel through a type of telescope. What happens to the light at point Y?

Arlen is exploring the ways that colors react to light. He adds red food coloring to four different beakers containing 150 milliliters of water each. He adds three drops of red food coloring to the first beaker, 15 drops to the second beaker, 30 drops to the third beaker, and 50 drops to the fourth beaker. He places all four beakers in the sunlight. After 15 minutes, he measures the temperature of the water in each beaker. What can he expect to find?

The temperature will increase as the color gets darker, because dark colors absorb more heat than light colors.

The temperature will decrease as the color gets darker, because more radiant energy from the Sun bonds to the food coloring.

The temperature will increase as the color gets darker, because the chemical bonds between the food coloring and water create additional energy.

The temperature will decrease as the color gets darker, because the dark colors reflect more light than the light colors.

While Kayden was swimming in the lake during the summer, his mother was standing on shore yelling for him to come and eat lunch. Not wanting to leave the lake, he pretended not to hear her by dunking his head in and out of the water. What happened to the sound waves of his mother's voice when his head was underwater

The sound waves moved faster in the water with a higher frequency, so he could still hear his mother.

The sound waves moved slower in the water and increased in energy, so he could still hear his mother.

The sound waves moved slower in the water with lower frequency, so he could not hear his mother.

The sound waves moved faster in the water and decreased in energy, so he could still hear his mother.

Which of the following is true of materials that are NOT completely transparent?

After the pitch, he saw the ball fly from the bat and then heard the crack of the bat a moment later. Which of the following explains why there was a difference between seeing ball fly and hearing the bat connect with the ball?

The light waves traveled with a faster speed in the air, allowing the ball to be seen first, while the sound waves moved with a slower speed in the air, causing the sound to be delayed.

The light waves traveled back from the sky, gaining energy, and the sound waves traveled in a straight line, losing energy, causing the sound to be delayed.

The light waves traveled with a lower frequency in the air, allowing the ball to be seen first, while the sound waves moved with a higher frequency in the air, causing the sound to be delayed.

The light waves traveled in a straight path, allowing the ball to be seen first, and the sound waves bounced up into the sky and had to be reflected back, causing the sound to be delayed.
