Sample questions
-
1.An electromagnetic wave has a frequency of 500 MHz and a wavelength of 60 cm. (a) Calculate the speed of the wave. (b) Name the medium through which it is travelling.
-
2.A ray of light is incident normally on a glass slab. What is the angle of refraction?
- A.0° because the ray passes undeviated when incident normally.
- B.90° because the ray bends away from the normal in the denser medium.
- C.45° as the ray splits equally between reflection and refraction.
- D.The angle depends on the refractive index of the glass slab.
-
3.In the atmosphere, which colour of visible light experiences the least amount of scattering?
- A.Violet
- B.Blue
- C.Green
- D.Red
-
4.23. A convex lens can be regarded as a set of prisms and a glass slab, such that refracting angle of the prisms
- A.continuously increases in outward direction
- B.remains same in outward direction
- C.continuously decreases in outward direction
- D.none of these
-
5.An object is placed in front of a concave lens at a distance of 45 cm from it. If its image is formed at a distance of 30 cm from the lens, calculate the focal length of the lens.
