If light is a electromagnetic wave

    now if light is an electromagnetic wave then why don't we realise the electromagnetic energy on lighting up a bulb or do we feel it? if yes then in what form?

    Hi,

    I'd say we do perceive the energy, e.g. we can see light with our eyes or we feel our skin gets warmer if exposed to sunlight. Sometimes, it can also be damaging if laser light comes into your eye you can become blind, or if your skin is exposed too long to sunlight, you get a sunburn.
