Question

What is the image distance when d0 =10.11 cm, f = 3.0 cm, di = ?

. Write down the lens formula (1/f = 1/o + 1/i)

. What happens in the simulation experiment when you change the focal length?

. What happens to the image if you change the object distance?

Describe the ray tracing - light tracing for the following:

. A Refracting telescope

. A Reflecting telescope

. A pair of binoculars. Porro Prism and Roof Prism binoculars.

. A microscope

. What happens to the image if you change the object size?

. Write down the Lens Maker's equation and explain

1/f = (n - 1 ) ( 1/R1 - 1/R2)

Answer 1

Ans 1

1/d0 + 1/d1 = 1/f

Where:

D0: Object distance ,
D1: Image distance ,
f: Focal length

Substituting the given values

We found out that image distance= 4.26cm
