Wavelength, Frequency, and Energy Practice Problems
1. A certain violet light has a wavelength of 413 nm. What is the frequency of this light?
2. What is the wavelength of radiation whose frequency is 1.50 x 1013Hz?
3. How much energy is associated with a photon in the microwave region of the spectrum with a frequency of 6.6 x 1012Hz?
4. A hydrogen lamp emits several lines in the visible region of the spectrum. One of these lines has a wavelength of 6.56 x 10-5cm. What is the energy of this radiation?
5. A very bright line in the bright-line spectrum of sodium has a wavelength of 590 nm. What is the speed of this wave?
