Properties of Waves

Front

What creates electromagnetic waves?

Back

The movement of protons and electrons creates electromagnetic waves, which generate a magnetic field.

Front

Which type of wave has more energy, A or B?

Back

Wave B has more energy.

Front

Which visible light color has the least amount of energy?

Back

Red has the least amount of energy among visible light colors.

Front

What happens to frequency when wavelength increases?

Back

When wavelength increases, the frequency decreases.

Front

Which wave has a lower frequency, A or B?

Back

Wave A has a lower frequency.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves have more energy, while lower frequency waves have less energy.

Front

What is the speed of electromagnetic waves in a vacuum?

Back

The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 300,000 km/s).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

How does the energy of a photon relate to its frequency?

Back

The energy of a photon is directly proportional to its frequency; higher frequency photons have higher energy.
