waves and wave properties

Front

What is the bending of light as it enters a new material called?

Back

Refraction

Front

In a longitudinal wave, what is the part where particles are packed closely together?

Back

Compression

Front

What is Snell's Law used for?

Back

To describe how light rays change direction when they pass from one medium to another.

Front

What is the index of refraction?

Back

A measure of how much a wave, such as light, slows down in a medium compared to its speed in a vacuum.

Front

What is the formula for Snell's Law?

Back

n1 * sin(θ1) = n2 * sin(θ2)

Front

What is a wavelength?

Back

The distance between successive crests or troughs in a wave.

Front

What is amplitude in wave properties?

Back

The maximum displacement of points on a wave from its rest position.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of a wave when it hits a surface, while refraction is the bending of a wave as it enters a new medium.

Front

What happens to light when it enters a denser medium?

Back

It slows down and bends towards the normal.

Front

What is rarefaction in a longitudinal wave?

Back

The part of the wave where particles are spread apart.
