Question

Instructions

Write the frequency, wavelength range, production and uses of electromagnetic waves.


​

Answer 1

The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 1025 Hz corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves.

Used in-

Radio waves.

Microwaves.

Infrared.

Visible light.

Ultraviolet radiation

Answer 2

• Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and magnetic field.
• The wavelength increase from approximately 10 raise to the power -18m to 100 km, and this corresponds to frequencies decreasing from 3 × 10 raise to the power 26 Hz to 3 × 10 raise to the power 3 Hz.
• Electromagnetic waves contains both electric and magnetic fields waves. This waves oscillate in perpendicular planes with respect to each other, and are in phase. The production of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.
• Electromagnetic waves are used to transmit long / short / Fm wavelength radio waves, and TV/Telephone/wireless signals or emergies. They are also responsible for transmitting energy into the form of microwave and such others things.

Hope this much helps you dear..
