What is the frequency f in Hz of light that has wavelength 157 nm? (Use

1 eV = 1.602 ✕ 10−19 J,

e = 1.602 ✕ 10−19 C,

c = 2.998 ✕ 108 m/s,

and

h = 6.626 ✕ 10−34 J · s = 4.136 ✕ 10−15 eV · s

as necessary.)

Answer #1

Summary: To calculate the frequency I only need the speed of light and wavelength of the light. So I applied the formula that velocity of light is equal to multiplication of frequency and wavelength and got the value of frequency of light.
