Question: The focal length of a converging lens is: - positive - negative - zero - infinite Converging Lens There are majorly two types of lens, converging and a diverging lens. he converging lens converges rays
If an object of height 4 cm is placed at a distance of 30 cm from the lens, find: The magnification produced by the lens. View Solution The focal length of a concave lens is 20 cm, if an object is placed at a distance of 50 cm in front of this concave lens, where is the ...
The focal length f is positive for converging lenses. True False Answer true or false: The focal distance of a concave mirror is positive. The focal length f is negative for diverging lenses. True False Choose true or false for the following statement regarding the sign conventions for mirrors...
To solve the problem step by step, we will follow these steps:Step 1: Identify the Focal Lengths - The focal length of the convex lens (f1) is +30 cm (positive because it is a convex lens). - The focal length of the concave len
Focal length extension is achieved by a concave lens which expands the beam path coming from the primary mirror. The lens can be fixed in the eyepiece holder or in the barrel body.KUGLER RUDOLF
