Self-Check Quiz Answers

Click each of the suggested answers below, and carefully compare your answers to the suggested answers.

If you have not done the quiz yet – STOP – and go back to step 1 above. Do not look at the answers without first trying the questions.

The camera’s computer interprets and adjusts the upside-down image signal to make it appear right-side-up. In a similar way, the human brain interprets the upside-down image from the eye as right-side-up.
Cones are light-sensitive cells that detect colour. With only one type of cone, dolphins have limited colour vision and are colour-blind to some colours.
The camera’s aperture will automatically open wider. This will let more light enter the camera to create a properly exposed image on the sensor.
Lenses bend light so that a focused image forms on the retina. Mirrors cannot be used in eyeglasses, because they would block light from entering the eye and they would reflect light away from the eye.
Light moves at very high speeds, so it can transmit information very quickly.
