ectromagnetic wave of frequency v 3 0 MHz passes from vacuum into a dielectric medium with relative permittivity 4 0 Then NEET Kar 2013 a wavelength is doubled and frequency is unchanged b wavelength is doubled and frequency becomes half c wavelength is halved and frequency remains unchanged d wavelength and frequency both remain unchanged
