Ultraviolet radiation has a frequency of 6.8*1015 Hz. What is the energy associated with this frequency?

Use Planck's equation (E=hv) to solve. where frequency (v) of ultrviolet radiation is 6.8 * 1015 1/s. The variable h is a constant equal to 6.63 * 10-34 J·s

E = (6.8 * 1015 1/s) x (6.63 * 10-34 J·s)
