A monochromatic light wave with wavelength \( \lambda_{1} \) and frequency \( v_{1} \) in air enters another medium. If the angle of incidence and angle of refraction at the interface are \( 45^\circ \) and \( 30^\circ \) respectively, then the wavelength \( \lambda_{2} \) and frequency \( v_{2} \) of the refracted wave are:
