If the wavelength of light is halved, what happens to the energy of the photons? (2020)
Step 1: Understand that light is made of particles called photons.
Step 2: Know that the energy of a photon is related to its wavelength.
Step 3: Remember the rule: Energy is inversely proportional to wavelength. This means that as the wavelength decreases, the energy increases.
Step 4: If the wavelength is halved, it means it is reduced to half its original size.
Step 5: Since the energy increases when the wavelength decreases, halving the wavelength will double the energy of the photons.
Photon Energy and Wavelength – The energy of a photon is inversely proportional to its wavelength, described by the equation E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength.
