really? no help. whats the point of this website
how do I figure this out, If someone can please guide me in steps as im struggling.
the question is: An object is 3cm high is placed 40cm in front of a thin +10.00D lens. Find the position and...
how do we find the centre thickness in sags?
im a bit confused what did you do with 10cm in front of a convex spherical surface how did you calculate that?
An object 2cm high is placed 25cm in front of a concave spherical surface of 15cm radius of curvature which separates air from glass of refractive index 1.75. Find the position and size of the...
An object 2cm high is placed 10cm in front of a convex spherical surface of 15cm radius of curvature which separates air from glass of refractive index 1.60. Find the position and size of the image.
hello..... i have a student who is doing the DO course and I had graduated DO course about 10 years ago. I have forgotten all the formulas. Not sure how to explain or show the student.
Here is...
