If you were comparing the yellow and blue wavelengths, which of the following statements is correct?

• The yellow lights frequency would be greater than the blue lights, but the yellow light’s wavelength is smaller than the blue lights.

• Both the yellow lights frequency and wavelength are greater than the blue lights.

• The blue lights frequency would be greater than the yellow lights, but the blue lights wavelength is smaller than the yellow lights.

• The blue lights frequency and wavelength are greater than the yellow light.

Carla shines a white light on a ripe banana and observes that it has a yellow color. What statement bests describes why the banana has a yellow color?

• The banana reflects red and blue light, making the banana appear yellow.

• The banana absorbs yellow light and reflects all other light.

• The banana reflects yellow light and absorbs all other light.

• The banana absorbs red and blue light, making the banana appear yellow.

A supernova (pictured above) occurs when a star explodes, giving off different types of light that travels through space. Scientists on earth are able to observe and measure the light that is emitted from it, but have never recorded any sound from the phenomena. What explanation best describes why scientists have been able to observe the light from a supernova, but not the sound?

• Sound waves travel at a much slower rate than light waves, therefore the sound waves will not make it to earth for a long time after the light waves.

• Sound waves cannot travel long distances, and thus cannot reach earth from the supernova’s location.

• Sound waves need matter to transmit the waves while light does not, since there is no matter in space sound waves cannot travel to earth.

• A supernova only produces light from the exploding star, not sound.

Louis performs a demonstration to model the behavior of light. He rolls a wet tennis ball toward a wall.The ball bounces off the wall. He observes the path of the ball by looking at the wet lines left on the floor, and finds that both the angle going toward the wall and the angle going away from the wall are the same.

What behavior of light is being modeled?

• Absorption

• Transmission

• Scattering

• Reflection

What real life scenario would use the same concept that Louis was showing in his demonstration

• Light goes through a prism and is bent at a 45 degree angle.

• Light shines through a magnifying glass, causing an object to appear larger

• Light shines on a car mirror so a driver can see the cars behind them.

• black object's temperature increases due to light shining on it.

You shine a flashlight on a glass of water. As you look on the other side of the glass, you notice a rainbow has formed on the table the glass is resting on. Which of the following explanations best describes what caused the rainbow to appear on the table?

• The light refracts causing the white light to split into its component colors.

• The water in the glass absorbs the light, causing the rainbow to form.

• The light refracts changing the color of the light.

• The rainbow is an illusion caused by your eyes.

• Black colored objects absorb less light than other colors.

• Black colored objects reflect less light than other colors.

• Black colored objects reflect more light than other colors.

• Black colored objects absorb more light than other colors.
