The table compares the wavelength of some unknown electromagnetic waves.

Comparison of Wavelength
Electromagnetic Wave Wavelength
A 10−4 m
B 10−6 m
C 102 m
D 100 m

Which electromagnetic wave has the lowest frequency?
Wave A
Wave B
Wave C
Wave D

Respuesta :

Answer:

Option C. (102 m)

Electromagnetic Wave having highest wavelength has the lowest frequency.

Explanation:

  • The relation between wave length and frequency of the electromagnetic  wave is inversely proportional if the wave is moving at a fixed speed.
  • So, the largest wave length of electromagnetic wave found during the comparison is 102 m so it must have the lowest frequency.
  • The mathematical relation is given as : v=fλ; where f stands for frequency, λ for wavelength and v for speed of wave.
