Consider a single photon with a wavelength of λ, a frequency of ν, and an energy of E. What is the wavelength, frequency, and energy of a pulse of light containing 100 of these photons?
A)100λ, 100ν, and E
B)0.01λ, ν, and 100E
C)λ, ν, and 100E
D)0.01λ, 0.01ν, and 0.01E
E)100λ, 100ν, and 100E
C)λ, ν, and 100E
Since energy is proportional to the number of photons, you often see energy of light expressed in joules per mole of photons (J/mol.) However, you will never see wavelength or frequency expressed in terms of moles. So the answer is C) λ, ν, and 100E.

Well, if I splice together 100 of these photons, it's like creating a laser light show! So, let's think about it. When you combine these photons, do you think the wavelength, frequency, and energy of the pulse of light will be 100 times the values of a single photon? Or maybe it will be just a fraction? Let's break it down:
A) 100λ, 100ν, and E: Hmm, this option seems to suggest that the wavelength and frequency are directly multiplied by 100, while the energy remains the same. That sounds like quite a power-packed pulse!
B) 0.01λ, ν, and 100E: This option implies that the wavelength becomes a tiny fraction, while the frequency and energy increase. Sounds like a funny warp in space-time, but probably not the correct answer.
C) λ, ν, and 100E: Ah, this option suggests that only the energy gets multiplied by 100, whereas the wavelength and frequency stay the same. That could be a reasonable outcome!
D) 0.01λ, 0.01ν, and 0.01E: Hmm, this option suggests that everything gets reduced by quite a bit. It's like shrinking a photon army. Not sure about this one.
E) 100λ, 100ν, and 100E: Ah, this option suggests that everything gets multiplied by 100. It's like having a photon party on steroids!
So, after some careful chuckles and pondering, I would have to go with option C) λ, ν, and 100E. It seems the most reasonable that the wavelength and frequency remain the same, while the energy gets a boost from 100 photons partying together. Enjoy the photon pulse shenanigans!
To find the wavelength, frequency, and energy of a pulse of light containing 100 photons, we need to consider the properties of a single photon and multiply them by the number of photons.
The number of photons does not affect the wavelength and frequency of each individual photon. Therefore, the wavelength and frequency of the pulse of light will be the same as that of a single photon. Let's denote this as λ′ and ν′.
The energy of a single photon, E, can be calculated using the equation E = hν, where h is Planck's constant.
To find the energy of the pulse of light, we need to multiply the energy of a single photon by the number of photons. Therefore, the energy of the pulse of light is given by 100E.
Now, let's consider the options:
A) 100λ, 100ν, and E: This option assumes that both the wavelength and frequency of the pulse of light are multiplied by 100, which is incorrect.
B) 0.01λ, ν, and 100E: This option assumes that the wavelength is divided by 100, which is incorrect. The frequency remains the same, and the energy is multiplied by 100.
C) λ, ν, and 100E: This option assumes that the wavelength and frequency of the pulse of light remain the same as a single photon, which is correct. The energy is multiplied by 100.
D) 0.01λ, 0.01ν, and 0.01E: This option assumes that both the wavelength, frequency, and energy of the pulse of light are divided by 100, which is incorrect.
E) 100λ, 100ν, and 100E: This option assumes that all the properties (wavelength, frequency, and energy) are multiplied by 100, which is incorrect.
Based on the explanations above, the correct answer is C) λ, ν, and 100E.
