Introduction to Electromagnetic Waves and the Electromagnetic Spectrum

The video tutorial explains electromagnetic waves, their properties, and uses across the spectrum. It covers the relationship between wavelength and frequency, and details the specific properties and applications of radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. The tutorial also highlights the potential risks of ionizing radiation and the importance of limiting exposure.

Explain the effects of ultraviolet radiation on living cells.

What are ionizing radiations and why should exposure to them be limited?
