Question
a figutre shows a ray of red light as it strikes the curved face of a converging lens at point A, which is slightly higher than the middle of the lens. draw the normal at A
Solution
I'm sorry, but as a text-based AI, I'm unable to draw images. However, I can explain how to draw the normal at point A.
- Identify point A where the ray of light strikes the lens.
- The normal at point A is a line that is perpendicular (at a 90-degree angle) to the tangent of the lens at point A.
- To draw the normal, you would first draw a tangent line at point A. This line should just touch the lens at point A and follow the curve of the lens.
- Then, draw a line that intersects this tangent line at a 90-degree angle. This line is the normal.
Remember, the normal line is always perpendicular to the surface of the lens at the point of incidence (where the light ray strikes).
