An electromagnetic wave of frequency n=3.0MHZ passes vacuumed into a dielectric medium with permeability £=4 then a. wavelength is doubled and the frequency remains unchanged b. wavelength is doubled and frequency becomes half c. wavelength is halved and frequency remains unchanged d. wavelength and frequency remains unchanged?
Verified Answer
An electromagnetic wave of frequency n=3.0MHZ passes vacuumed into a d...
C ∝ 1/√ε  C → 1/2 ; as ε → 4

∴ C = nλ

λ becomes 1/2

n frequency remains unchanged

The correct option is C.
