Wave behaviors

Front

What is an echo?

Back

An echo is a sound wave that reflects off a hard surface and returns to the listener.

Front

What is absorption in wave behavior?

Back

Absorption is when energy from a wave is not transferred through or reflected by the medium, but instead goes into the medium.

Front

What is a convex lens?

Back

A convex lens is a curved piece of glass that bends light toward a central focal point.

Front

What happens to light when it moves from air to water?

Back

The light slows down when it moves from air to water.

Front

What is transmission in wave behavior?

Back

Transmission is the process where light passes through a medium without being absorbed or reflected.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is the difference between reflection and transmission?

Back

Reflection is when light bounces off a surface, while transmission is when light passes through a medium.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a point in a given period of time, usually measured in Hertz (Hz).

Front

What is amplitude in wave behavior?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, related to the energy of the wave.

Front

What is a concave lens?

Back

A concave lens is a lens that diverges light rays that are entering it, causing them to spread out.
