Answer:

(1) True, Ozone, In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen.

(2) False, The power of the lens is the reciprocal of the focal length of the lens. This is the focal length of the convex lens. Hence, The focal length of the lens is 20 cm.
