What is the energy of a photon of a red light having a frequency 4.48 x 10 14Hz?

Answer 1

Since the wavelength times the frequency is equal to the speed of the wave, all you need to do in this case is divide the speed of light (in meters/second) by the frequency. The answer will be in meters.

Answer 2

For calculating the energy, use E=h x f

where

E= energy of the radiation,

h=Planck's constant=6.626 x 10-34

and f=frequency of radiation

E=6.626 x 10-34 x 4.6 x 1014 =28.4918 x 1020 Joules

Answer 3

Wavelength = speed/frequency

In vacuum, wavelength = 299,792,458/4.72 x 1014 = 635.15 nanometers

(Red light, not much shorter than the limit of visibility for the human eye.)

Answer 4

I'll give you the equation to figure it out. E=hf, where h is Planck's constant, and f is the frequency.

Answer 5

Wavelength = (speed of light) / (frequency) = (3 x 108 / 4.56 x 1014) = (3 / 4.56) x 10-6 = 6.579 x 10-7 meter(rounded)

Answer 6

4.56e14 Hz = 6.5744e-7 meters wavelength

Answer 7

The energy is 2,9685.10e-19 joule.

Answer 8

635 nm (ap3x)
