Gamma-ray bursters are objects in the universe that emit pulses of gamma rays with
high energies. The frequency of the most energetic bursts has been measured at around
3.0 × 10
21
Hz.
The speed of light is 3 × 10
8 m/s.
What is the wavelength of these gamma
rays?

  • Physics -

    wavelength = (speed of light)/(frequency)
    = 3*10^8/3.0*10^21 = 10^-13 m

  • Physics -

    4.2 x 10^13

  • Physics -

    4.2 x 10^13 is wrong
