Question

name the waves of electromagnetic spectrum and also mention their wavelengths and frequencies

Answer 1

1) Radiowave :-
wavelength = 3× 10¹⁴ -3× 10^7 ( in A° )
frequency = 10^5 Hz - 10^9 Hz

2) microwave :-
wavelength = 3× 10^7 A° - 6×10^6 A°
frequency = 10^9 Hz - 5 × 10¹¹ Hz

3) infrared wave :-
wavelength = 6×10^6 A° - 7600A°
frequency = 5× 10¹¹ Hz - 3.95 × 10¹⁴ Hz

4) visible wave :-
wavelength = 7600 A° - 3800 A°
frequency =3.95 × 10¹⁴ Hz -7.9× 10¹⁴ Hz

5) Ultraviolet rays ;-
wavelength = 3800A° -150 A°
frequency = 7.9×10¹⁴ Hz - 2× 10^16 Hz

6) X-rays :-
wavelength = 150 A° -0.1 A°
frequency = 2× 10^16 Hz - 3×10^18 Hz

7) Y-rays :-
wavelength = 0.1 A° - 0.01A°
frequency = 3×10^19Hz - 3× 10^20 Hz

8) cosmic rays :-
wavelength = 0.01 A° -zero
frequency = 3× 10^20 Hz - infinity
