Question

Different types of electromagnetic waves have different wavelengths. Which of these electromagnetic waves has the longest wavelength?

x-rays

radio waves

ultraviolet light

gamma rays

Answer 1

The Electromagnetic Spectrum consists of radio waves, microwaves (a type of radio wave), infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays. Waves with the longest wavelengths have the lowest frequencies. Waves with the shortest wavelengths have the highest frequencies. will this help? hope it does.

Answer 2

The electromagnetic waves which has the longest wavelength is: B. radio waves.

An electromagnetic wave refers to a wave that do not require any medium for its propagation and as such, it can travel through an empty space or vacuum.

The different types of electromagnetic waves with their wavelengths are listed below:

• X-rays: 0.01 - 10 nanometer.

• Radio waves: greater than 400 nanometer or 100 kilometer.

• Ultraviolet (UV) light: 1 nm - 400 nanometer.

• Gamma rays: less than 1 nanometer.

In conclusion, radio waves have the longest wavelength in the electromagnetic spectrum.
