Incident ray x passes parallel to the principal axis of a concave lens. incident ray y passes parallel to the principal axis of a convex lens. how do the rays behave differently after passing through each lens? ray x continues moving in the same direction, and ray y refracts and passes through the focal point located behind the lens. both rays refract and move as though they passed through the focal point. ray x appears as though it passed through the focal point in front of the lens, and ray y passes through the focal point on the other side of the lens. both rays continue moving in the same directio

Answer :

The correct option is (C) " Ray X appears as though it passed through the focal point in front of the lens, and ray Y passes through the focal point on the other side of the lens ".

Explanation :

It is given that, incident ray X passes parallel to the principal axis of a concave lens. In concave lens ( also known as the diverging lens ), the ray appears as it passed through the focus as shown in figure 1.

When incident ray Y passes parallel to the principal axis of a convex lens ( also known as the converging lens ), it will pass through the focal point of the lens as shown in figure 2.

Hence, the correct option is (C).

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

this is a good question! i'll do some research and come back when i have the answer!
