Explain how a prism can split white light into a spectrum of colours.
Question 7
7.
Describe what we can say about the angle of incidence and the angle of reflection
Question 8
8.
Explain using your knowledge of light why light bends as it enters and leaves the glass prism
Explain how the direction of light changes when it passes from air into water. Include an explanation of the concept of refraction.
Light bends towards the normal line because it slows down in water.
Light speeds up and bends away from the normal line in water.
Light travels in a straight line without bending.
Light bends away from the surface as it exits water.
Describe how light is involved in the process of vision. Include details about how light interacts with the eye.
Light enters the eye, passes through the lens, and focuses on the retina to create an image.
Light creates an image on the surface of the eye, which is sent directly to the b
The eye releases light that travels to objects, forming an image.
Light is absorbed by the pupil, creating a visual image in the brain.
Explain why objects appear a certain color in daylight but may appear different under artificial lighting. Relate your answer to how light behaves.
Objects change color because artificial lights emit different wavelengths than sunlight.
Objects reflect artificial light differently, altering their texture.
Artificial lights are brighter and make colors fade.
Light behaves the same under all lighting, so colors remain the same.
Compare and contrast transparent, translucent, and opaque materials, providing an example for each.
Transparent materials let no light through; translucent let all light through; opaque let some light through.
Transparent materials let all light through, like glass; translucent let some light through, like frosted glass; opaque let no light through, like wood.
Transparent materials scatter light, translucent block some light, opaque focus l
