Reflect Refract Absorb

Front

What is absorption in the context of light?

Back

Absorption is the process by which an object takes in light energy, converting it into other forms of energy, such as heat. For example, a black object absorbs all colors of light.

Front

What happens to light when it hits a black surface?

Back

When light hits a black surface, it is absorbed, meaning that the surface takes in the light energy rather than reflecting or transmitting it.

Front

Define reflection in terms of light waves.

Back

Reflection is the bouncing back of light waves when they encounter a surface. For example, a mirror reflects light, allowing us to see our image.

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, such as from air into water, causing objects to appear distorted.

Front

What is the difference between reflection and refraction?

Back

Reflection involves light bouncing off a surface, while refraction involves light bending as it passes through different materials.

Front

What does it mean for an object to be transparent?

Back

A transparent object allows light to pass through it without significant scattering, enabling us to see through it, like clear glass.

Front

What does it mean for an object to be opaque?

Back

An opaque object does not allow light to pass through it; instead, it reflects or absorbs all the light that hits it.

Front

What is the role of a lens in light behavior?

Back

A lens refracts light to focus or disperse it, commonly used in glasses, cameras, and microscopes.

Front

How does color affect light absorption?

Back

The color of an object affects how it absorbs light; darker colors absorb more light, while lighter colors reflect more light.

Front

What is the principle of light transmission?

Back

Light transmission is the process by which light passes through a material. Transparent materials transmit light, while opaque materials do not.
