Physics Chapter 11 electromagnetic waves

What is the Nature of Electromagnetic waves?

Sunlight can be split into a continuous spectrum of colours. The rainbow

spectrum is just one small section on the spectrum of electromagnetic

waves. As seen from the video earlier on, the continuous electromagnetic wave

spectrum covers a large range of wavelengths and frequencies . In the electromagnetic spectrum, electromagnetic waves are arranged in

order of their frequency or wavelength.

What wave has the highest frequency?

Gamma rays

Which wave has the highest wavelength

Radiowaves

Does all electromagnetic waves travel at the same speed?

Yes, all electromagnetic waves can travel without a medium with the same speed of 3 × 10 to the power of 8 m/s.

What type of wave is electromagnetic waves?

All electromagnetic waves are transverse waves.

What is wave speed equation?

Velocity = Frequency x wavelength
