Refraction & Reflection of Light

Reflection and Refraction

Reflection Of light and Refraction at plane surface

Reflection of light and Refraction of light .

High-quality camera lenses are often coated to prevent reflection. A lens has an optical index of refraction of 1.72 and a coating with an optical index os refraction 1.31. For near normal incidence, the minimum thickness of the coating to prevent reflection for wavelength of 5.3 xx 10^(-7) m is

Reflection, Neutralization, Refraction, Dispersion.

STATEMENT -1 : If reflected or refracted ray diverge from a point, the image will be virtual. and STATEMENT - 2 : After reflection or refraction the refracted or reflected rays appear to meet at a point on principle axis. They do not actually meet at a point.
