A wave is traveling at the speed of light. If it has a frequency of 4 x 10^15 Hz, what is its wavelength?

Respuesta :

Answer:

7.5x10-^8m

Explanation:

the formulae is v=fh ,where f is frequency

h is wavelength

hence wavelength=v/f

since the speed of light is 3x10^8

then the wavelength =3 x 10^8/4 x 10^15

=7.5x10^-8m
