Calculate the energy (in nJ) of a photon emitted by a mercury lamp with a frequency of 6.88 x 10¹⁴ Hz.

A light ray has a wavelength that is 835 µm contains 6.32 x 10^-3 J of energy. How many photons does this light ray have?

How much energy (in kJ) do 4.50 moles of photons contain at a wavelength of 705 nm?

How are wavelength, frequency, and energy related for photons of light?

What is the longest wavelength of radiation with enough energy to break carbon-carbon bonds?

Hospital X-ray generators emit X-rays with wavelength of about 15.0 nanometers (nm), where 1nm = 10⁻⁹ m. What is the energy of a photon of the X-rays?

Calculate the energy of the violet light emitted by a hydrogen atom with a wavelength of 410.1 nm.
