Answer
The power of a glass plate is zero because its parallel surfaces do not converge or diverge light rays. The emergent rays remain parallel to the incident rays, it is only laterally displaced. Hence, the focal length of a glass plate is infinite.
Hence, using the below formula and on putting focal length =
,
Hence, the power of a glass plate is zero.
