Question 2

If a photon has an energy of $E$ and a momentum of $p$, which of the following expressions correctly relates these two quantities, given that the speed of light is $c$?

Question 3

An astronomer observes a distant quasar and detects electromagnetic radiation with a frequency of $3 \times 10^{17} \text{ Hz}$. In which region of the electromagnetic spectrum does this radiation primarily fall?

Question 4

When considering the energy-frequency relationship of photons, if a photon's frequency is halved, what happens to its energy?

Question 5

A photon of light has a wavelength of $500 \text{ nm}$. Given Planck's constant $h = 6.626 \times 10^{-34} \text{ J\cdot s}$ and the speed of light $c = 3.00 \times 10^8 \text{ m/s}$, calculate the energy of this photon in Joules.
