What is the wavelength of a wave with a frequency of 101,050 Hz? c=𝜆𝜈

Question

What is its energy? E= hv

Answer 1

As I mentioned in your other question, in the equation c = λν, c is the speed of light (2.998 x 10⁸ m/s) and ν is the frequency which you are given as 101,050 Hz (where Hz is 1/s), and λ is the wavelength. So, rearranging the equation λ = c/ν. Just plug in the numbers to get λ (wavelength) in meters.

The same goes for energy, ν again is the frequency (101,050 1/s) and h is Planck's constant which is 6.626 x 10-34 m2kg/s. Just plug in the numbers to get energy in joules.
