The electromagnetic spectrum spans a variety of radiation types including x-rays all the way through to radio waves. Humans are able to only see in the visible part of the electromagnetic spectrum (390-700nm) but bees can see ultraviolet radiation (10-100nm). Lower wavelength electromagnetic waves have more energy. Hence, compared with humans, bees can sense electromagnetic waves that have more energy.
the radius of the earth in himalayan region is greater than terai reagion. therefore, the value of 'g' at the poles is greater than the value of g at the equator. 12
