Ray diagrams can be used to determine the image location, size, orientation and type of image formed of
objects when placed at a given location in front of a mirror.The reflection of light is what we are getting here.
Let us see one example on it .
Question:-
An object is 15 cm from a spherical concave mirror having a 20 cm radius. Locate the image by means of: the mirror equation?
ANSWER: - 30 cm
The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows:
1/ do +1/f = 1/ di
f=-r/2= - 20/2=-10 cm
So here di = - 30 cm
Here the image is – 30 cm from the mirror
