Question

Multiply choice/short answer Match the following descriptions to either a converging lens or a diverging lens: i) Lens that causes parallel rays to refract toward the optical axis. Light goes from medium A into medium B. If you measure that the angle the rays make with the normal in A is less than the angle they make with the normal in B. then you can conclude that the refractive index of A is less than the refractive index of B. lf the electric field strength produced by a point charge is 1000 N/C at 10.0 cm from this charge, where will the strength be 25.000 N/C?

Explanation / Answer

in case of converging lens, the parallel light rays refracting toward its prinicipal axis.

option A is correct.

the reduced and virtual images produced by the diverging lens.

so, option B is correct.

diverging lens thicker at its edges compared to center of the lens.

so, option B is correct.

----------------------------------------------------------------------------------------------

n1sin@A = n2sin@B

(c/vA)sin@A = (c/vB)sin@B

if the light raytravels from high refractive indexmedium to lower refractive index

medium, the light ray bent away from the normal due to refraction. So, the given

statement is false.

-----------------------

electric field:

   E = kq/r^2

   E2/E1 = (r1/r2)^2

new distance is,

    r2 = [sqrt(E1/E2)]*r1= [sqrt(1000/25000)]*10= 2 cm

option ii is correct
