Diffraction, Reflection, Refraction

Front

What is reflection?

Back

Reflection is the bouncing of light off the surface that it strikes on.

Front

What is the main difference between refraction and diffraction?

Back

Refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle.

Front

What is the best explanation for Mickey seeing himself in the mirror?

Back

Reflection.

Front

What causes light to appear refracted?

Back

The speed of light changes as it travels through different materials.

Front

Refraction is when light__________.

Back

Changes speed as it travels in different materials which causes bending.

Front

What is diffraction?

Back

Diffraction is the bending and spreading of light waves around obstacles.

Front

What is the law of reflection?

Back

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

Front

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

Back

It slows down and bends towards the normal line.

Front

What is the normal line in the context of reflection and refraction?

Back

The normal line is an imaginary line perpendicular to the surface at the point of incidence.

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.
