Electromagnetic Spectrum

Front

What is the electromagnetic spectrum?

Back

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

Front

Which type of electromagnetic radiation has the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

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 formula to calculate the energy of a photon?

Back

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

Front

How do you calculate the frequency of light given its wavelength?

Back

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

Front

What color of light has the longest wavelength?

Back

Red light has the longest wavelength in the visible spectrum.

Front

What color of light has the shortest wavelength?

Back

Violet light has the shortest wavelength in the visible spectrum.

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 frequency of light with a wavelength of 5.06 x 10^-7 m?

Back

The frequency is approximately 5.93 x 10^14 Hz.

Front

What is the energy of a photon with a frequency of 7.39 x 10^14 Hz?

Back

The energy of the photon is approximately 4.88 x 10^-19 Joules.
