Ray optics - geometrical optics (covered by lecture Introduction to Optical Modeling) The topic of “Ray optics – geometrical optics” is not covered in the course “Fundamentals of modern optics”. Problem 3: Two plane mirrors are inclined to each other such that a ray of light incident on first mirror and parallel to the second is reflected from the second mirror parallel to the first mirror. Light propagates inside the fibre, which is made of glass which has a higher refractive index than the air outside. An image is thus a point-to-point correspondence with the object established through reflection and/or refraction. Which of the following is true about light? Photometry is a branch measurement of light energy. NCERT 12th class Physics exemplar book solutions for chapter Ray Optics and Optical Instruments are available in PDF format for free download.
