EXAMPLE OF ELECTROMAGNETIC SPECTRUM
Answer:
- gamma-rays 1020 – 1024 < 10-12 m
- x-rays 1017 – 1020 1 nm – 1 pm
- ultraviolet 1015 – 1017 400 nm – 1 nm
- visible 4 x 1014 – 7.5 x 1014 750 nm – 400 nm
- near-infrared 1 x 1014 – 4 x1014 2.5 μm – 750 nm
- infrared 1013 – 1014 25 μm – 2.5 μm
- microwaves 3 x 1011 – 1013 1 mm – 25 μm
- radio waves < 3 x 1011 > 1 mm
Radio waves, microwaves, infrared waves, visible light, ultraviolet light, and even X-rays and gamma rays are all part of the electromagnetic spectrum! In a lot of respects, all of these electromagnetic waves are the same. To begin with, all electromagnetic waves are capable of traveling through empty space. Electromagnetic waves, unlike sound waves or water waves, do not require a medium to move through. This is significant because the light and heat from the Sun would not be able to reach us on Earth if electromagnetic waves could not travel through empty space!
