If two photons in a vacuum have a different energies, what can we say about the wavelengths of these photons?

Question

A) the wavelength depends only on color, not on energy

B) the higher-energy photon has the shorter wavelength

C) They have the same wavelength; all photons have the same wavelength, regardless of energy/

D) the higher-energy photon has the longer wavelength

a,b,c, or d?

Answer 1

B.

Very easy to demonstrate. Take a rope, tie it to something and then take the other end and move it up and down.

If you do it easy and slow (low energy), you will have long waves and could do it all day.

However, if you speed it up (high energy), the waves become shorter, but you will tire faster because it take more energy.

I find it sometime easier to remember things like this by picturing things like that in my head.

Answer 2

the more the mass ratio of the proton to the electron the faster the electron has to rotate to maintain a distance from the proton by centrifugal force, and the faster the rotation the shorter the wave length, and the by product is not only measurable by the visible colour spectrum, but also composed of all frequencies.
so the answer is B

Answer 3

B is the answer...E=h/w.....where w=wavelength and h is a constant
thats very intuitive ,walking man

Answer 4

b.
Energy is equal to Planck's constant times the frequency.
