Diving birds often dive straight down if they want to catch a fish. explain why?
a ball is thrown vertically upwards with a given velocity u such that it rises for T seconds(T>1),what is distance traveled by the ball during the last one second of ascent(in metres)?
A particle moving with certain velocity has the de-broglie wavelength of 1 Angstrom. For particle B with mass 25 % and velocity 75 % of A. calculate de-broglie wavelength

Download the collection of questions asked in previous CBSE board exams from the chapter Wave Optics.
Practising the previously asked questions is a good idea to prepare for the exams.
It is always better to know the chapterwise marks distribution before you start studying.
