Aconcave lens of power -2d is placed in contact with a convex lens of power +1.5d what will be the resultant power

Answers

Answer from: nshuey0930

-0.5 D

Explanation:

The resultant power can be defined as the sum of powers of all the lenses placed in contact together.

P =P₁ + P₂ + P₃ +

It is given that power of the concave lens is, P₁ = -2 D

Power of the convex lens is, P₂ = +1.5 D

Thus, the resultant power when these two lenses are placed in contact with each other are: P = P₁ + P₂ = -2 D + 1.5 D = -0.5 D.

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.
