Problem 4.189

An electromagnetic wave of frequency v=3.0MHzv=3.0 \mathrm{MHz} passes from vacuum into a non-magnetic medium with permittivity ε=\varepsilon= =4.0.=4.0 . Find the increment of its wavelength.

Reveal Answer
Δλ=(1/ε−1)c/v=−50 m\Delta \lambda=(1 / \sqrt{\varepsilon}-1) c / v=-50 \mathrm{~m}
