Question

The point C is the centre of curvature, the image formed by the refraction in the situation shown in figure is
[ ] U=1.0 u= 1.5 C С 25cm 20cm

a) 100 cm from left of separating surface
b) 50 cm from left of separating surface
c) 90 cm from left of separating surface
d) 70 cm from left of separating surface​

Answer 1

Answer:

⇒v=−200×0.5=−100cm

So, the image is 100cm from (P) the surface on the side of S.

Answer 2

Answer:

What do you want to mean there a lot of physics mangification, velocity- initial and final,displacement is is from Mirror of spherical.

So, it is a concave or convex ??
