A concave mirror collects light from a distant star. How far from the mirror is the image of the star if the radius of curvature is 150 cm?
As the distance from the star can be considered as infinite, the focal length is equal to R/2 = 1.50m/2 = 0.75 m, we can use the formula: 1/f = 1/d0 + 1/d1 = 1/∞ + 1/d1 -1/0.75 = 1/d1 d1 = - 0.75. The image is at 0.75m away from the mirror.
I'm extremely satisfied with your work. Excellent quality. Always.
Just have a question. Do you also provide help in understanding a concept? Not an assignment but for my learning. If certain concepts in the book are not clear, can you provide a simplified explanation of it using math that's understandable? You can charge the equivalent of an assignment.
Some things in the chapter attachments I sent you are not clear. They do not have much solved examples either.
Thanks a lot,
