The UV graph for a convex lens is a :A. Straight line passing through the originB. Straight line having a y-interceptC. ParabolaD. Hyperbola

The correct answer is B. Straight line having a y-intercept.

The UV graph for a convex lens represents the relationship between the object distance (U) and the image distance (V). It is derived from the lens equation:

1/f = 1/V - 1/U

Where f is the focal length of the lens. The UV graph is obtained by plotting the values of U on the x-axis and V on the y-axis.

For a convex lens, the UV graph is a straight line that intersects the y-axis (V-axis) at a specific point, representing the image formed when the object is at an infinite distance (U approaches infinity). This point of intersection corresponds to the focal length of the lens. Hence, the graph is a straight line with a y-intercept.

So, the correct answer is B. Straight line having a y-intercept.
