An electron of mass m and a photon have same energy E. The ratio ofde-Broglie wavelengths associated with them is(c being velocity of light)
(1). \(\displaystyle c\left(2mE\right)^{1/2}\)
(2). \(\displaystyle \frac{1}{c}\left(\frac{2m}{E}\right)^{1/2}\)
(3). \(\displaystyle \frac{1}{c}\left(\frac{E}{2m}\right)^{1/2}\)
(4). \(\displaystyle \left(\frac{E}{2m}\right)^{1/2}\)
