Behavior of Light - SC.7.P.10.2

(SC.7.P.10.2) The illustration shows what happens when two different colors of light strike a glass object. What can you conclude from the illustration?

• The glass reflects the red light.
• The glass refracts the red light.
• The glass does not transmit light.
• The glass absorbs the red light.

(SC.7.P.10.2) Even if an object does not produce light, it is still visible. Why is this possible?

• The object is large.
• The object absorbs light.
• The object reflects light.
• The object is familiar.

(SC.7.P.10.2) Kareem told his friend about the beautiful rainbow he saw just after a rainstorm. Kareem then explained to his friend how a rainbow forms. What was Kareem’s explanation?

• The light waves were refracted by moisture in the air and separated into colors.
• The intensity of light increased as the waves passed through tiny droplets of water.
• Light traveled faster after the rainstorm because of the moisture in the air.
• Tiny droplets of water reflected the light waves that struck them.

(SC.7.P.10.2) Light from the sun causes the moon to be visible at night. Which of the following causes the moon to be visible?

• refraction
• absorbtion
• optical illusion
• reflection

(SC.7.P.10.2) Katie used a flashlight to find her way through her backyard in the dark. Her best friend Clarice followed slowly behind her. After a few minutes, Katie was several feet ahead of her. Clarice then found it difficult to see where to walk because the light from Katie’s flashlight was dimmer. What caused the light to be dimmer for Clarice?

• absorption of the light by the particles in the air
• refraction of the light as it travels through the air
• transmission of the light through the night darkness
• reflection of the light by the ground

(SC.7.P.10.2) Light can be reflected, refracted, and/or absorbed. Which of the following best explains how light can be changed?

• Absorption causes a change in the color of light.
• Refraction causes a change in the intensity of light.
• Reflection causes a change in the color of light.
• Refraction causes a change in the direction of light.

(SC.7.P.10.2) Light can sometimes create an optical illusion. For example, you may see something under water and reach into the water to pick it up. However, the object is not where you thought it would be. What property of light is responsible for this optical illusion?

• reflection
• transmission
• refraction
• absorption

(SC.7.P.10.2) To save energy, some people install solar panels on their homes as shown in the illustration below. What interaction between solar panels and sunlight enables people to save on energy?

• The energy of the sunlight is absorbed by the solar panels
• The energy of the sunlight is reflected by the solar panels.
• The energy of the sunlight is refracted by the solar panels.
• The energy of the sunlight is transmitted through the house.

(SC.7.P.10.2) Look closely at the illustration below of different beams of light reacting with an object. Which beam of light illustrates the law of reflection?

• 4
• 2
• 1
• 3

(SC.7.P.10.2) Light that is reflected off of objects can be detected by our eyes. This is why you can see your image in a mirror. Why can’t you see your image reflected off of a wall?

• Your eyes detect all of the reflected light.
• A wall absorbs all of the light that strikes it.
• Not all of the light that reflects off of a wall is directed toward your eyes.
• Light waves do not travel far after striking an object such as a wall.
