Front

What is the amplitude of a wave?

Back

The amplitude of a wave is the maximum distance that the wave's particles move from their rest position. It is a measure of the wave's energy.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, where the wave's particles are at their minimum displacement from the rest position.

Front

How is wavelength defined in waves?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as from crest to crest or trough to trough.

Front

What part of the electromagnetic spectrum can humans see?

Back

The visible spectrum is the part of the electromagnetic spectrum that is visible to the human eye, typically ranging from about 400 nm to 700 nm.

Front

How do you calculate the frequency of a wave?

Back

Frequency (f) can be calculated using the formula f = c / λ, where c is the speed of light (approximately 3.00 x 10^8 m/s) and λ is the wavelength.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 3.00 x 10^8 meters per second.

Front

What is the formula to find the energy of a photon?

Back

The energy (E) of a photon can be calculated using the formula E = h * f, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency.

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

What is the difference between visible light and infrared light?

Back

Visible light is the part of the electromagnetic spectrum that can be seen by the human eye, while infrared light has longer wavelengths than visible light and is not visible to the human eye.
