Reflect, refract, and absorb

Front

What does 'absorb' mean in the context of light?

Back

Soaking up light.

Front

What is the process called when a microscope lens bends light?

Back

Refraction.

Front

What is an example of refraction?

Back

A picture showing light bending as it passes through a lens.

Front

What is an example of reflection?

Back

A picture showing light bouncing off a surface, like a mirror.

Front

How does light behave when it hits a mirror?

Back

It reflects off the surface.

Front

What is the law of reflection?

Back

The angle of incidence is equal to the angle of reflection.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different mediums.

Front

What happens to light when it is absorbed by a material?

Back

The light energy is converted into other forms of energy, such as heat.

Front

What is total internal reflection?

Back

A phenomenon that occurs when light travels from a denser medium to a less dense medium and is completely reflected back into the denser medium.

Front

What is the critical angle in optics?

Back

The minimum angle of incidence at which total internal reflection occurs.
