“is it true or wrong that a light wave is a transverse wave? if yes give its reason, if wrong justify it.”

A Light wave is a Transverse wave.

Yes

Explanation:

The Light waves are a kind of electromagnetic waves. It is known that all electromagnetic waves are transverse waves.

The transverse waves oscillates perpendicular to the direction of propagation.

As light waves moves perpendicular to the propagation direction of electric and magnetic field, it falls under transverse wave.

So it can be confirmed that light wave is a transverse as it is a kind of electromagnetic wave.

The transverse waves are sinusoidal in nature.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
