Expert Solution & Answer
To determine
To find:
a) What appears on a distant viewing screen at a point at which the top and bottom rays through the slit have a path length difference equal to 5λ.
b) What appears on a distant viewing screen at a point at which the top and bottom rays through the slit have a path length difference equal to 4.5λ.
Answer to Problem 1Q
Solution:
a) m=5 minimum.
b) Maximum between the m=4 and m=5 (approximately).
Explanation of Solution
1) Concept:
Usingthe condition for occurrence of minimum in a single slit experiment, we can find what appears on a distant viewing screen at a point at which the top and bottom rays through the slit have a path length difference equal to 5λand4.5λ.
2) Formula:
∆L=mλ
3) Given:
The single slit experiment is conducted with the light of wavelength λ.
4) Calculations:
a) In the single slit experiment, the condition for occurrence of minimum is
Pathlengthdifference=∆L=mλForm=1,2,3
From this, we can interpret that at ∆L=5λ;m=5 minimum appears.
b) ∆L=4.5λ implies that it corresponds to approximately maximum between m=4minimumandm=5minimum.
Conclusion:
We can predict about what appears on screen in a single slit experiment from the condition for minimum.

For each of the actions depicted below, a magnet and/or metal loop moves with velocity v→ (v→ is constant and has the same magnitude in all parts). Determine whether a current is induced in the metal loop. If so, indicate the direction of the current in the loop, either clockwise or counterclockwise when seen from the right of the loop. The axis of the magnet is lined up with the center of the loop. For the action depicted in (Figure 5), indicate the direction of the induced current in the loop (clockwise, counterclockwise or zero, when seen from the right of the loop). I know that the current is clockwise, I just dont understand why. Please fully explain why it's clockwise, Thank you
A planar double pendulum consists of two point masses \[m_1 = 1.00~\mathrm{kg}, \qquad m_2 = 1.00~\mathrm{kg}\]connected by massless, rigid rods of lengths \[L_1 = 1.00~\mathrm{m}, \qquad L_2 = 1.20~\mathrm{m}.\]The upper rod is hinged to a fixed pivot; gravity acts vertically downward with\[g = 9.81~\mathrm{m\,s^{-2}}.\]Define the generalized coordinates \(\theta_1,\theta_2\) as the angles each rod makes with thedownward vertical (positive anticlockwise, measured in radians unless stated otherwise).At \(t=0\) the system is released from rest with \[\theta_1(0)=120^{\circ}, \qquad\theta_2(0)=-10^{\circ}, \qquad\dot{\theta}_1(0)=\dot{\theta}_2(0)=0 .\]Using the exact nonlinear equations of motion (no small-angle or planar-pendulumapproximations) and assuming the rods never stretch or slip, determine the angle\(\theta_2\) at the instant\[t = 10.0~\mathrm{s}.\]Give the result in degrees, in the interval \((-180^{\circ},180^{\circ}]\).
