Answer:
0.572 Hz
Explanation:
given,
length of simple pendulum, l = 0.76 m
mass of the bob, m = 365 g = 0.365 Kg
angle made from the vertical, = 12°
frequency, f = ?
f = 0.572 Hz
The frequency at which pendulum vibrates is equal to 0.572 Hz
Answer:
= 1220 nm
= 1.22 μm
Explanation:
given data:
wavelength
distance of screen from slits D = 3 m
1st order bright fringe is 4.84 mm
condition for 1 st bright is
---( 1)
and
= 0.0924 degrees
plug theta value in equation 1 we get
condition for 1 st dark fringe
= 2λ since from eq (1)
= 1220 nm
= 1.22 μm
