Hello everyone.
00:01
So in a situation according to a numerical, he says the object is a 10 cm long.
00:07
That means the h1 is equivalent to a 10 centimeter.
00:11
And he is placed at the distance of a 15 cm, that is a convex length.
00:17
Okay guys, this is your convex lens.
00:21
Now this is a convex lens.
00:25
So u is a negative sign that is a minus of a 15 centimeter.
00:31
And second thing is given, okay, that is a focal length.
00:36
So focal length of that particular lens is a plus of a 10 centimeter.
00:42
Now we are considered that equation.
00:44
So 1 upon v minus 1 upon u is equivalent to a 1 upon f, clear? so 1 upon v is unknown, minus 1 upon u is a minus of a 15 is equivalent to 1 upon 10 students...
