283058 A plane wave front is incident on a thin prism, thin convex lens and a concave mirror separately. The wave front(s) emerging out from the

1 concave mirror is plane
2 thin prism is spherical
3 convex lens and concave mirror are plane
4 convex lens and prism are plane
5 convex lens and concave mirror are spherical

283059 A single-slit diffraction pattern is obtained using a beam of red light. What happens if the red light is replaced by blue light?

1 There is no change in the diffraction pattern
2 Diffraction fringes become narrower and crowded together
3 Diffraction fringes become broader and farther apart
4 Diffraction pattern disappear
