Wave properties

What is the definition of frequency in physics?

Frequency is defined as the number of cycles or oscillations per second.

What are mechanical waves?

Mechanical waves include sound, water, seismic waves, and waves on springs or ropes.

What are electromagnetic waves?

Electromagnetic waves include radio, microwave, infrared, light, ultraviolet, x-ray, and gamma rays, which are oscillations in magnetic and electric fields.

Can electromagnetic waves travel through a vacuum?

Yes, electromagnetic waves can travel through a vacuum, like space.

What is wavelength?

Wavelength is the distance from a point on one wave to the same point on the next wave, measured in meters and denoted by the Greek letter lambda.

What is amplitude?

Amplitude is the height of the wave from the rest position to the peak or trough, measured in meters.

How is frequency measured?

Frequency is measured in hertz (Hz).

What is the speed of electromagnetic waves in a vacuum?

Electromagnetic waves travel at the speed of 300,000 kilometers per second in a vacuum.

What happens to the energy of a wave as its amplitude increases?

The more energy a wave has, the bigger the amplitude.

What is the relationship between frequency and the number of waves passing a point?

Frequency is the number of waves passing a point every second.
