MCQ

In a Young's double slit experiment, the angular width of fringe formed on a distant screen is $0.1$ $radian$ . Find the distance between the two slits, if wavelength of light used is $6000\,\mathop A\limits^o $....$\mu m$

A
$12$
B
$3$
✓
$6 $
D
$601$

✓

Answer

Correct option: C.

$6 $

c
In $YDSE$

$\theta = \frac{\lambda }{d} = 0.1 \Rightarrow d = \frac{\lambda }{\theta } \Rightarrow d = 6\,\mu m$

A monochromatic light is incident on a metallic plate having work function $\phi$. An electron, emitted normally to the plate from a point A with maximum kinetic energy, enters a constant magnetic field, perpendicular to the initial velocity of electron. The electron passes through a curve and hits back the plate at a point B. The distance between A and B is:
