Wave Behaviors & Interactions

Front

What is reflection?

Back

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

Front

The angle produced as a source of light bounces off a reflecting surface is called ______.

Back

angle of reflection

Front

What does it mean to reflect?

Back

bounce off

Front

Refraction is when light__________.

Back

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

Front

What is a general definition of wave interference?

Back

When more than one wave meet and interact in the same medium.

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

Front

What is total internal reflection?

Back

It occurs when light hits a boundary at an angle greater than the critical angle, causing all the light to be reflected back into the medium.

Front

What is the critical angle?

Back

The angle of incidence above which total internal reflection occurs.

Front

What is constructive interference?

Back

When two waves meet in phase and their amplitudes add together, resulting in a larger wave.
