Electromagnetic Spectrum

Front

What happens to the energy of a photon as the frequency of the wave increases?

Back

The energy increases.

Front

What is the formula to calculate the frequency of light?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases, and vice versa.

Front

What is the energy of a photon with a frequency of 7.39x10^14 Hz?

Back

E = hv = 4.88x10^-19 J.

Front

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

Back

E = hv, where E is energy, h is Planck's constant, and v is frequency.

Front

What is the wavelength of light with an energy of 7.56x10^-19 J?

Back

λ = hc/E = 2.62x10^-7 m.

Front

What is the speed of light in a vacuum?

Back

Approximately 3.00 x 10^8 m/s.

Front

What color of light corresponds to a wavelength of approximately 5.06x10^-7 m?

Back

Green.

Front

How do you convert wavelength to frequency?

Back

Use the formula v = c/λ.

Front

What is the frequency of light with a wavelength of 4.22x10^-7 nm?

Back

7.11x10^14 Hz.
