Electromagnetic Spectrum; Frequency and Wavelength

Front

What is the term for the particles of light that are involved in the photoelectric effect?

Back

Photons

Front

Which type of electromagnetic wave has the longest wavelength?

Back

AM radio waves.

Front

What is the formula to calculate the frequency of a wave given its wavelength?

Back

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

Front

If a beam of light has a wavelength of 6 x 10^-7 m, what is its frequency?

Back

5 x 10^14 Hz.

Front

What is the energy of a photon with a wavelength of 12.3 nm?

Back

1.62 x 10^-17 J.

Front

What are radio waves classified as in terms of their wavelength?

Back

Long wavelength electromagnetic waves.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.0 x 10^8 m/s.

Front

How does the wavelength of a wave relate to its frequency?

Back

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

Front

What is the electromagnetic spectrum?

Back

The range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is the relationship between energy and frequency of a photon?

Back

Energy is directly proportional to frequency; E = hf, where E is energy, h is Planck's constant, and f is frequency.
