1.	Radio waves : Longer than about 20 cm :: Infrared waves ___________
Answer» Radio waves : Longer than about 20 cm :: Infrared Rays : LONGER THAN 780 nm Let's learn a few facts about ELECTROMAGNETIC waves: Electromagnetic waves propagate at a VELOCITY of 3 × 10⁸ m/s. They contain 2 components : electrical component and a magnetic component. If we SEE the electromagnetic spectrum, we will observe that Gamma rays have a least wavelength (highest frequency) and Radio waves have highest wavelength (lowest frequency). In the electromagnetic spectrum, there is a group of waves, which fall under visible spectrum (containing all the visible light rays like RED, violet, blue, etc.) The wavelength of the electromagnetic spectrum begin from 10^(-16) m and range upto 10⁸ metres. The visible spectrum ranges from 400 nm upto 720 nm. $\star$ Hope It Helps.

Radio waves : Longer than about 20 cm :: Infrared Rays : LONGER THAN 780 nm

Let's learn a few facts about ELECTROMAGNETIC waves:

Electromagnetic waves propagate at a VELOCITY of 3 × 10⁸ m/s.

They contain 2 components : electrical component and a magnetic component.

If we SEE the electromagnetic spectrum, we will observe that Gamma rays have a least wavelength (highest frequency) and Radio waves have highest wavelength (lowest frequency).

In the electromagnetic spectrum, there is a group of waves, which fall under visible spectrum (containing all the visible light rays like RED, violet, blue, etc.)

The wavelength of the electromagnetic spectrum begin from 10^(-16) m and range upto 10⁸ metres.

The visible spectrum ranges from 400 nm upto 720 nm.
