Which describes a relationship when calculating the energy of a photon?

The energy of the photon is directly proportional to frequency.
The energy of the photon is inversely proportional to frequency.
As the energy of the photon increases, Planck’s constant increases.
As the energy of the photon increases, Planck’s constant decreases.

Energy of photon is calculated by:
$$E=\frac{ hc }{ \lambda}$$

ramirocruzo · Answer

Or you can write it as:$$E=h \nu$$ Where, v is Frequency

As for Plank's Constant, its name defines that it is constant....So, how can it change??? ;D

anonymous · Answer

so would it increase constantly ?

ramirocruzo · Answer

Nope, constants are universal values that never change....

anonymous · Answer

still clueless :/

ramirocruzo · Answer

Look to derive proportionality, we collaborate all the constants into one...
$$E=h \nu$$$$E=\nu C$$ Where, C is a constant and never cant change,
$$E ∝ h$$
Thats all.....So what do you think???

b?

ramirocruzo · Answer

A

ramirocruzo · Answer

E∝h Means that if E increases, v increases alongside linearly .....

ooh i see. thanks for helping me :)
