How do scientists determine the energy and frequency of photons?

Explanation:

the energy of photon can be determined by the formula that is

E=hf where h is plancks constant and its value is 6.63*10^-34 j.s and f is the frequency of photon to find out the frequency we have to divide the energy of photon by plancks constant

f=E/h

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
