Waves & Energy Test 1

Mia, Abigail, and Anika are conducting a science experiment. They shine a light through a glass of water and observe the light bending. What does this phenomenon demonstrate?

• absorption

• reflection

• refraction

• scattering

Elijah is studying the behavior of waves in his physics class. He noticed something when a transverse wave interacts with a piece of wood. What did Elijah observe?

• The wave turned into an electromagnetic wave.

• The frequency of the wave changed.

• Vibrations occurred in the wood.

• The wavelength of the wave changed.

Avery, Ava, and Daniel are studying the properties of light in their physics class. They are particularly interested in blue and red light. How do blue light and red light differ?

• Their wavelengths are the same, they don't differ.

• Their wavelengths are different.

• Red light only carries energy.

• Blue light only carries energy.

During a science experiment, Benjamin created a fire by pouring gasoline into a container. Samuel threw a log into a pond, David poured water into a brownie mix, and another student blew air into a trumpet. Which student's action is MOST likely to create a light wave?

• Samuel throwing a log into the water

• Benjamin creating fire from gasoline

• David pouring water into a brownie mix

• The student blowing air into a trumpet

Arjun, Aria, and Liam are playing with a flashlight in a dark room. Arjun points the flashlight at a mirror. What happens to the light from the flashlight when it hits the mirror?

• Light is absorbed in the mirror.

• Light goes through the mirror.

• Light bounces off (scatters) from the mirror.

• Light is refracted on the mirror.

Evelyn, Elijah, and Grace are studying different types of waves in their physics class. They noticed that two waves are identical. How could these waves be the same?

• They have the same frequency.

• They have the same amplitude.

• They have the same pitch.

• They have the same wavelength.

Anika, Isla, and Sophia are studying the electromagnetic spectrum in their science class. They are discussing how it relates to light. What is the correct statement?

• All the waves on the electromagnetic spectrum look the same to the human eye.

• The waves on the electromagnetic spectrum all have the same wavelength.

• Our eyes are able to see a few of the waves on the electromagnetic spectrum and see different colors.

• Our eyes cannot see any waves on the electromagnetic spectrum.

Jackson, Benjamin, and Nora are studying waves in their physics class. They are looking at images of a longitudinal wave and a transverse wave. Which of the following is true about these images?

• Neither wave has a wavelength.

• Neither wave uses energy to move.

• Both waves have wavelengths.

• Both waves are soundwaves.

During a class, Michael claps his hands to get the attention of Aria and Ava. How is the sound produced when Michael claps his hands?

• A vibration in the air occurs when the hands hit each other and a sound occurs.

• The hands reflect off of the skin and sound is formed.

• The clapping creates a wind tunnel, which causes the sound.

• Heat energy causes the sound to occur.

During a science experiment, Michael, Ava, and Daniel were discussing why they can't hear each other's voices if they were in outer space. What's the reason?

• Nobody is there to hear it.

• There is no oxygen in space.

• There is no medium/matter in space.

• It's too hot in space.
