Where is the magnetic field of a current element (i) minimum and (ii) maximum?
The correct relation between the refractive index ( mu ) of the material of prism (A) and angle of minimum deviation ( delta ) is
If the refractive index of material of a prism is sqrt3 , then angle of minimum diviation of the prism, which is equilateral is
In which of the following cases will the mutual inductance be (i) minimum (ii) maximum?
A ray of light is incident at an angle of 60^(@) on the face of a prism with an angle of 60^(@) . Then the refractive index of the material of the prism is (the prism is in minimum deviation position)
The refracting angle of a prism is A, and refractive index of the material of the prism is cot (A//2). the angel of minimum deviation is
