in science exam we had a question to design an experiment to find the focal length of a concave mirror using a distant object ....
So in tht question i took the object sun . So it will be right na because many of my other classmates have taken distant tree or distant window bt only i hv taken as the object
So can u tell me if it is correcr to take that ?? Only class 10 students ans who rreally know d answer no spamming !!!!

Yess it is correct because rays from infinity and the image is formed at focus so we calculate focal length

yes! this will be become currect but on the big scale measurement because you need a total distance for focal length that wiil be very very big if we seen this from sun.But easy from a tree to window.
