Light

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another.

Front

What is the difference between reflection and refraction?

Back

In reflection, light bounces off a surface and does not pass through, while in refraction, light passes through and bends.

Front

Why does a fork look different when placed underwater?

Back

The fork looks different underwater because light is refracted at an angle as it moves from water to air.

Front

What occurs when light hits a mirror?

Back

When light hits a mirror, it is reflected off the surface.

Front

What happens to light that strikes a black sweatshirt?

Back

Most of the light that strikes a black sweatshirt is absorbed.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

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 be completely reflected back into the medium.

Front

What is the critical angle in optics?

Back

The critical angle is the angle of incidence above which total internal reflection occurs.

Front

How does the speed of light change when it enters a denser medium?

Back

The speed of light decreases when it enters a denser medium.

Front

What is dispersion of light?

Back

Dispersion of light is the separation of light into its component colors due to different degrees of refraction.
