What is a quantum of light called? a. a photon b. an electron c. planck's constant d. an electromagnetic wave

Option ( A) is correct.

A quantum of light is called a photon.

Light is made of these packets of energy called as photons. These photons have zero rest mass.They possess momentum and travel with the velocity of light. They are electrically neutral. The energy of the photon is given by

E= h f

E= energy of photon

h= planck's constant

f= frequency of the photon

The higher frequency photons have more energy as compared to the lower frequency photons.

f=ma newton

f=100x2.5=250n

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
