Electromagnetic Spectrum Review

Front

What is the electromagnetic spectrum?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

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 calculate energy of a photon?

Back

E = hv, where E is energy, h is Planck's constant (6.626 x 10^-34 J·s), and v is frequency.

Front

What is Planck's constant?

Back

Planck's constant is a fundamental constant used in quantum mechanics, valued at approximately 6.626 x 10^-34 J·s.

Front

What is the formula to calculate frequency from wavelength?

Back

v = c/λ, where v is frequency, c is the speed of light, and λ is wavelength.

Front

What are energy levels in the Bohr model?

Back

Energy levels are specific orbits around the nucleus where electrons are found, each corresponding to a certain energy state.

Front

True or False: Electromagnetic waves require a medium to travel.

Back

False. Electromagnetic waves can travel through a vacuum.
