Do electromagnetic waves carry energy and momentum?

Text Solution

Verified by Experts

Electromagnetic waves like any other waves carry energy and momentum as they travel through empty space. If light didn't carry energy, it wouldn't be able to heat up the stuff that comes in its path or generate photo current in photo cells.
Energy carried by electromagnetic wave :
`E=hv=(hc)/(lamda)`
`"and momentum "P=Ec`
