Light Energy 5.6C

Front

What is refraction in the context of light?

Back

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed.

Front

What happens to light when it travels from air into water?

Back

Light slows down and bends, which is an example of refraction.

Front

Define reflection in terms of light behavior.

Back

Reflection is the bouncing back of light when it hits a surface that does not absorb the light.

Front

What is an example of reflection in everyday life?

Back

Looking at your image in a mirror or a shiny surface, like a silver spoon.

Front

How does the angle of incidence relate to the angle of reflection?

Back

The angle of incidence is equal to the angle of reflection when light reflects off a surface.

Front

What is the significance of the medium in light behavior?

Back

The medium determines how light travels, refracts, or reflects based on its properties.

Front

Why do objects appear distorted when viewed through water?

Back

Objects appear distorted due to the refraction of light as it passes from water to air.

Front

What is the role of a lens in manipulating light?

Back

A lens refracts light to focus or disperse it, creating images.

Front

Explain how light behaves when it passes through a prism.

Back

Light refracts at different angles depending on its wavelength, causing dispersion into a spectrum of colors.

Front

What is total internal reflection?

Back

Total internal reflection occurs when light hits a boundary at an angle greater than the critical angle, causing it to reflect entirely back into the medium.
