Some important key points :- • the angle of incident is equal to angle of reflection. • the incident Ray, the normal to the mirror at the point of incident & the reflected ray, all lie on the same plane. • diameter = aperture • mirror formula = 1/f = 1/v + 1/u • linear magnification = height of image/ height of object m = h'/h or m = - v/u • the incident Ray & normal to the interface of two transparent Media at the point of incidence, all lie in the Same plane • the ratio of sine angle of incidence to the sine angle of refraction is a constant fir a given pair of media. This is known as Snell's law of refraction. •sin i/sin r = constant • Lens formula = 1/v - 1/u = 1/f • SI unit = diopter (D) • power = 1/focal length or P = 1/f

Best lecture for light chapter. Understood very well😄and definitely going to recommend all the students who are struggling with science 😑(especially physics 😢).

in my class 9th icse , i was having a hard time with chapter light and didnt know how to decribe nature of the image formed. so i got 11/20 marks in that physics test but after i watched this video and start understandiing the concepts i got full marks in exam of that light part. But one thing i always crave for that show some real life practical experiments to justify your answer . Dear Physics Wallah

Sir, In fourth image formation of concave mirror... • First ray travels parallel to principal axis n after reflection passes through principal focus... • second ray passes through principal focus and after reflection travel parallel to principal axis... Bt in our NCERT books It is given that... Second ray passes through centre of curvature of the concave mirror n after reflection, is reflected back along the same path So... Can we use the same method u did for image formation?

@yourfatherrr

Жыл бұрын

For me go for ncert as for board point of view, questions will be based on ncert diagrams. But the diagram which sir has drawn is almost similar to the ncert diagram apart from the points which light rays had fall. Basically, they both are same in image formation

I am just entering class 10th and I am really really scared of physics 😰😱 .... But now when I came to know about Rakshak sir, it's appear that Physics is not too much hard as I thought. And one more thing-- If in future, I will do my 12th with physics... Then for this the credit goes to only Rakshak sir. Thank you so much sir.... ☺☺👍👍
