What is the wavelength (in nm) of light having a frequency of 7.8 × 1013 Hz? What is the frequency (in Hz) of light having a wavelength of 5.54 × 102 nm?
speed of wave = wavelength * frequency wavelength = speed / frequency where speed of light is 3.0 * 10^8 hence wavelength = 3.79 * 10^-5 frequency = wavelength/speed = 1883.6
