If light is a electromagnetic wave

Click For Summary
SUMMARY

The discussion centers on the nature of light as an electromagnetic wave and its perceptible effects on humans. Participants assert that while light is indeed an electromagnetic wave, its energy is perceived through visual sight and thermal sensations, such as warmth from sunlight. Additionally, the conversation highlights the potential dangers of light exposure, including blindness from lasers and sunburn from prolonged sunlight exposure.

PREREQUISITES
  • Understanding of electromagnetic wave theory
  • Basic knowledge of human sensory perception
  • Familiarity with the effects of light on biological tissues
  • Awareness of laser safety protocols
NEXT STEPS
  • Research the properties of electromagnetic waves in detail
  • Study the human eye's response to different wavelengths of light
  • Explore the biological effects of UV radiation on skin
  • Learn about laser safety and eye protection measures
USEFUL FOR

This discussion is beneficial for physicists, educators in optics, health professionals concerned with UV exposure, and anyone interested in the interaction between light and human biology.

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.
