What are wavelengths less than a meter?

Answer 1

Microwaves have very long wavelengths, on the order of 1 - 1000 meters. Visible light has much shorter wavelengths, on the order of 10^-9 meters. In between would be something like infrared (IR) with wavelengths in the range of about 0.3 mm to 700 nm (7x10^-7 m).

Answer 2

Wavelengths less than a meter include radio waves, microwaves, and infrared radiation. These shorter wavelengths are commonly used in technologies such as wireless communication, radar systems, and heat sensing applications.

Answer 3

All electromagnetic phenomena ... radio, AM, FM, NPR, SSB, microwave, TV, PBS, Fox, taxicab, police,

fire, radar, cellphone, sheriff's deputy, 3G/4G WiMAX, infra-red, ambulance, visible light, UVA, UVB, heat,

x-ray, gamma ray, cosmic ray ... everything with frequencies greater than 300 MHz, has a wavelength of

less than 1 meter.
