Answer:
691.13 nm
Explanation:
d = width of the slit = 0.11 x 10⁻³ m
θ = angle of diffraction pattern = 0.72° degree
λ = wavelength of the light = ?
m = order = 2 (since second minimum)
for the second minimum diffraction pattern we use the equation
d Sinθ = m λ
Inserting the values
(0.11 x 10⁻³) Sin0.72 = (2) λ
λ = 691.13 x 10⁻⁹ m
λ = 691.13 nm
The correct choice is ' D ' .

1# The ball flying through the air has two types of energy, kinetic from its velocity and potential from its height off the ground.
Answer:
530.5 Hz
Explanation:
Given :
C=0.75 micro
L=120 mH
Reactance capacitor can be determined by
=
where c =capacitor
= 
Reactance inductor can be determined by
As they are in series so ,
On solving these value we get
As we know that
f = 
=
530.5 Hz
