A) 5A B) 0.49A C) 0.69A D)-5A 13) In a single-slit diffraction experiment, the width of the slit through which passes is reduced. What happens to the width of the central bright fringe in t resulting diffraction pattern? A) It stays the same. B) It becomes narrower. C) It becomes wider 14) What principle is responsible for light spreading as it passes through a n slit? A) refraction B) polarization C) diffraction D) dispersion 15) A beam of light of wavelength 610 nm passes through a slit that is 1.9 wide. At what the angle away from the centerline does the first dark fring A) 9.35 B) 11.4° C) 12.20 D) 18.7°

Explanation / Answer

10. Ray model of light

-------

11. Inductor stored energy in terms of magnetic field.

-----

12.

Using equilibrium of forces

BiL= mg

i= mg/(BL)

= 1.5*10^-3*9.8/( 05* 0.06)

= 0.49 A

-------

13.

It beacomes wider.

-----

14. That phenomenon is called diffraction.

-----

15.

Sin x= m*L/d. (I)

m=1

L= 610*10^-9

d= value of d is get cropped

Put all values to find x

Comment in case any doubt.. goodluck
