If light is a electromagnetic wave

[ahsaas]

now if light is an electromagnetic wave then why don't we realize 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.

I can explain that light is indeed an electromagnetic wave, but it is a specific type of electromagnetic wave that is visible to the human eye. This means that when we see light, we are actually seeing the energy of the electromagnetic wave.

When a light bulb is turned on, it emits this electromagnetic energy in the form of photons, which are particles of light. These photons travel through the air and enter our eyes, where they are detected by specialized cells called photoreceptors. These photoreceptors then send signals to our brain, which interprets the information as light.

So while we may not physically feel the electromagnetic energy from a light bulb, we are able to perceive it through our sense of sight. This is because our eyes are specifically designed to detect and interpret this type of electromagnetic energy.

In summary, the reason we do not physically feel the electromagnetic energy from a light bulb is because our bodies are not equipped to detect it in that way. Instead, we are able to perceive it through our sense of sight.
