Class 10 Science | Chapter 10 Light - Reflection and Refraction | Important Questions and Quick Revision

Blue light with a wavelength of 425 nm passes from a vacuum into a glass lens, and the index of refraction is found to be 1.65. The glass lens is replaced with a plastic lens. The index of refraction for the plastic lens is 1.54. In which one of the two lenses does the light have the greatest speed and what is that speed ?

What is the speed of light in glass of refractive index 1.5 ? Given speed of light in water is 2.25 xx 10^8 m//s and refractive index of water is 1.3 .

Lens : Refraction of light :: Mirror : _________

A ray of light after refraction through a concave lens becomes parallel to the principal axis after refraction through the concave lens. Explain with a ray diagram when this can happen.
