Question

Please use text to type out the answer, no pictures please thank you.

The equation E=hf describes the energy of each photon in a beam of light. If Planck’s constant, h, were larger, would photons of light of the same frequency be more energetic or less energetic. Be sure to explain using at least 3 content related sentences.

Answer 1

1) The value of planck's constant is positive, so is energy and frequency.

As per the relation, energy is directly proportional to frequency, if planck's constant remain unchanged.

2) If we take that frequency is remains constant and (somehow) planck's constant increases, the we will have a direct relation between energy and planck's constant

3) therefore the energy contained in the photon beam of same frequency would be higher in that beam for which value of planck's constant is more and that beam would be more energetic.
