An electromagnetic wave of frequency v= 3.0 MHz passes from vacuum into a dielectric medium with permittivity ? = 4.0. 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 both remain unchanged.
