Consider a single photon with a wavelength of lambda, a frequency of nu, and an energy of e. what is the wavelength, frequency, and energy of a pulse of light containing 100 of these photons? 0.01 lambda, nu, and 100e 0.01 lambda, 0.01 nu, and 0.01 e 100 lambda, 100 nu, and e 100 lambda, 100 nu, and 100 e lambda, nu, and 100e

lambda , nu , and 100E

Explanation:

The energy of a photon is given by:

  (1)

Where:

is the Planck constant

is the frequency

On the other hand, we have an expression that relates the frequency of the photn with its wavelength :

(2) where is the speed of light

Substituting (2) in (1):

  (3) This is the energy for a single photon

For 100 photons, the energy is:

  (3)

Where the wavelength and the frequency of the light remains constant.

Therefore, the answer is:

, , and 100E

answer: good job it's all correct !

explanation:

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
