Page Number: 168 Question 1 Define the principal focus of a concave mirror. Answer: The principal focus of a concave mirror is a point on its principal axis to which all the light rays which are parallel and close to the axis, converge after reflection from the concave mirror. Question 2 The radius of curvature of a spherical mirror is 20 cm. What ...

The speed of light in vacuum is 3 x 108 ms-1. Answer-. Refractive index of a medium (nm) = Speed of light in vacuum/Speed of light in the medium. Speed of light in vacuum (c) = 3 × 10 8 m/s. Refractive index of glass (ng) = 1.50. Speed of light in the glass (v) = Speed of light in vacuum/ Refractive index of glass.

According to the wave theory, light consists of electromagnetic waves. The light waves travel with a very high speed of 3 × 108 m/s in vacuum. The wavelength of visible light waves lies between 4 × 10–7 m to 8 × 10–7 m. The phenomenon of diffraction (bending of light around the corners of tiny objects) interference and polarization of ...
