Define The greenhouse effect on earth.

Explain the blackbody radiation and its effect?

To correct the vision of a hyperopic eye, a corrective lens should enable the wearer to focus on objects that are as close as the ideal near point. One way to think of this is that the corrective lens should take an object located at the ideal near point and create an image of it at the wearer's near point. (Remember that the wearer's eye is a short distance behind the corrective lens.) Draw a ray diagram showing this situation and find the necessary focal length of the lens in terms of the wearer's near point, the ideal near point, and the distance between the corrective lens and the eye.
