Review for Common Assessment #2

Why does the object look bent in the image?

• the light is refracting in the water causing it to look bent

• the light is reflecting in the water, causing waves to bounce in difference directions to your eyes

• the light is absorbed in the water, so no light waves are moving to your eyes for the bottom

• the light is scattering, so the image is going in many directions to your eye

Which 2 of the following are true about this image?

• The only reason you see the tennis ball is because the light rays are leaving the light and bouncing off of the tennis ball.

• Light is bouncing off in all directions, but since some reaches your eyes you would be able to see part of the ball.

• The tennis ball is emitting the light to areas around it, so that is why we are able to see it.

• Light is reflecting off the ball straight back to the light... and that light is then reaching our eyes.

• When the light is off, there is still light emitting from the ball that our eyes can see.
