WebJan 15, 2024 · Ray Optics Handwritten Notes PDF: A light ray is a line (straight or curved) that is perpendicular to the light’s wavefronts; its tangent is collinear with the wave vector.Light rays in homogeneous media are straight. They bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes. WebApr 3, 2024 · The distance between the focus F and the pole P of the mirror is called the focal length of the mirror, denoted by f. If R be the radius of curvature of the mirror then …

Webif light is incident normally on boundary. refractive index of 1 st medium = refractive index of 2 medium. When light ray undergoes refraction, there is a change in its velocity and … WebSolution. Let c 1 and c 2 be the velocities of light in air and glass respectively. Using the definition of refractive index. μ = c1/c2. orc 2 = c1/ μ. c 2 = 3 x 108/1.5 = 2 x 108 m/s. Since frequency remains same when light passes from one medium to another. Therefore c 1 = λ 1 f c 2 = λ 2 f. Now μ = c1/c2 = λ1/λ2.
