Wave Speed in Different Mediums

Front

What happens to the speed of electromagnetic waves when they transition from air to glass?

Back

The speed of electromagnetic waves decreases when they pass from air into glass.

Front

What do waves transfer?

Back

Waves transfer only energy, not matter.

Front

How does the speed of light in water compare to its speed in air?

Back

The speed of light is slower in water than in air because the molecules are closer together.

Front

Which medium allows electromagnetic waves to travel the fastest?

Back

The vacuum of space allows electromagnetic waves to travel the fastest.

Front

What is the term for the distance between the calm sea and the highest wave?

Back

Amplitude.

Front

What is the speed of sound in air compared to its speed in water?

Back

The speed of sound is generally faster in water than in air due to the closer proximity of molecules.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed is equal to frequency multiplied by wavelength (v = f × λ).

Front

What is the effect of temperature on the speed of sound in a medium?

Back

The speed of sound increases with an increase in temperature in a medium.

Front

What is refraction in the context of wave speed?

Back

Refraction is the bending of waves as they pass from one medium to another, causing a change in speed.

Front

How does the density of a medium affect the speed of sound?

Back

Generally, the greater the density of a medium, the slower the speed of sound, although this can vary depending on the medium.
