Does wavelength multiplied by the frequency equals the energy?

Answer 1

Wavelength lambda and frequency f are connected by the speed c of the medium.

c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s.

c can be light waves or electromagnetic waves = 299 792 458 m/s.

The formulas are:

c = lambda x f - That is frequency times wavelength.

f = c / lambda

lambda = c / f

frequency is nu so the equation is actually c= lamda x nu
That could be the speed of sound or the speed of light. c = f times lambda

Answer 2

Yes, in the context of electromagnetic waves (like light), the energy of a photon is directly proportional to its frequency and inversely proportional to its wavelength. The energy of a photon is given by the equation E = hf, where E is energy, h is the Planck constant, and f is frequency.

Answer 3

Wavelength lambda and frequency f are connected by the speed c of the medium.

c can be air = 343 m/s at 20 degrees celsius or water at 0 dgrees = 1450 m/s.

c can be light waves or electromagnetic waves = 299 792 458 m/s.

The formulas are:

c = lambda x f

f = c / lambda

lambda = c / f

WHAT???

Answer 4

Wavelength is a measurement of distance, frequency is a measurement of cycles per unit time and appears as (1/ Time) so for example:

(meters) * (1/ seconds) = meters/second which is velocity.

----------------------------------------------------------------

Hence the product of wavelength and frequency of the wave would give the velocity of the wave. that is C (speed of light) = nu x lambda.

The Greek symbol nu is for the frequency and lambda for the wavelength.

In case of light wave its value in air or vacuum is 3 x 10^8 m/s.

Hence for a visible light of wavelength 5000 Angstrom its corresponding frequency is got from frequency = speed of light *wavelength

3 x 10^8 / 5 x 10^-7

So this leads to 6 x 10^14 hertz.

Answer 5

Frequency times wavelength equals the speed of the wave in the medium.

It can be derived using defining units: wave/time x distance/wave = distance/time.

Answer 6

It equals the Constant Speed of Light (3.00 x 108 meters per second). This can also be abbreviated by the letter c.

Answer 7

That's the speed of the wave.

Answer 8

The waves velocity.

Answer 9

That's the speed of the wave.

Answer 10

That is equal to the speed of the wave.
