Chapter 4 Math Chemistry

Determine the energy in joules of a photon whose frequency is 3.55 x 10^17 Hz.

2.35 x 10-16 joules

Calculate the wavelength of the electromagnetic radiation whose frequency is 7.500 x 10^12 Hz.

4.000 x 10^-5 nm

Determine the frequency of light whose wavelength is 4.257 x 10^-7 cm

7.047 x 10^16 Hz

When sodium is heated, a yellow spectral line whose energy is 3.37 x 10^-19 J per photon is produced. What is the frequency of this light? What is the frequency of this light?

Frequency = 5.09 x 10^14 Hz Wavelength = 5.89 x 10^-7 nm
