Answer:
The wavelength of radio waves is much longer than the wavelength of visible light waves
Explanation:
Electromagnetic waves are periodic oscillations of the electric and the magnetic fields, occuring in a plane perpendicular to the direction of motion the wave.
Electromagnetic waves are the only waves able to travel in a vacuum; they travel at the speed of light:
Electromagnetic waves are also classified into 7 different types, according to their wavelength/frequency. From longest to shortest wavelength, we have: (with the corresponding wavelength written in the brackets):
Radio waves (>1 m)
Microwaves (1 mm - 1 m)
Infrared (750 nm - 1 mm)
Visible light (380 nm - 750 nm)
Ultraviolet (10 nm - 380 nm)
X-rays (0.01 nm - 10 nm)
Gamma rays (<0.01 nm)
So from the table, we can see that:
The wavelength of radio waves is much longer than the wavelength of visible light waves.
