Question

Give the range of wavelengths of the following e.m. waves:
(i) Radio Waves (ii) Microwaves : (iii) Ultraviolet; (iv) x-rays.

Answer 1

Dear Student,

◆ Range of wavelengths for EM waves -

(i) Radio Waves

• Wavelength > 100 mm

(ii) Microwaves

• Wavelength = 0.1 mm to 100 mm

(iii) Ultraviolet

• Wavelength = 10 nm to 400 nm

(iv) X-rays

• Wavelength = 1 nm to 10 nm

● Electromagnetic waves-

• Electromagnetic waves refers to the waves propagating through space, carrying electromagnetic radiant energy.
• Electromagnetic waves can travel through vacuum.
• It doesn't need matetial medium to transfer energy from one medium to another.
• It transfers energy through vibrations of electric and magnetic fields.

# Types of EM waves-

1. radio waves
2. microwaves
3. infrared rays
4. visible light
5. ultraviolet rays
6. X-rays

Thanks dear...
