Problem
A ray of light traveling in water is incident on its surface open to air. The angle of incidence is θ , which is less than the critical angle. Then there will be [2007]
(1) only a reflected ray and no refracted ray
(2) only a refracted ray and no reflected ray
(3) a reflected ray and a refracted ray and the angle between them would be less than 180∘−2θ
(4) a reflected ray and a refracted ray and the angle between them would be greater than 180∘−2θ
