Question

Photons travel outward from a light bulb in

Answer 1

Photons:

According to quantum mechanics light is not a wave but it posses particle nature and light travel in the form of packets of energy and each packet of energy is known as photon or quanta. These photons can travel in all direction from a source like bulb.

The shape of a bulb is nearly spherical and light or photons emitted in all the direction.

Answer 2

The correct answer is "in all direction." Protons travel outward from a light bulb in all different directions. Protons are subatomic particles with a positive charge. This subatomic particle is being emitted by the bulb to when light travels.
