What are at least two differences between ultraviolet rays and microwaves?

Answer 1

Microwaves are electromagnetic radiation with frequencies in the range from 300 MHz (0.3 GHz) to 300 GHz although some sources restrict their definition to the 3 GHz to 300 GHz range.

Ultraviolet rays are electromagnetic radiation with wavelengths in the range from 10 nm to 400 nm (frequencies from 2.99x107 to 7.5x105 GHz)

Clearly the frequencies are quite different.

Also - since the frequencies are so different, UV filters may not filter microwaves and vice-versa. Sunblock may protect you from getting a sunburn from UV rays but it won't block microwaves at all. Similarly, absorption of the two forms of radiation is quite different. Microwaves can heat a cup of soup up very nicely while you could die of starvation waiting for UV rays to heat it up.

Answer 2

1. Wavelength: Ultraviolet rays have shorter wavelengths than microwaves.
2. Effects: Ultraviolet rays can cause skin damage and increase the risk of cancer, while microwaves are primarily used for cooking and heating food.
