Question
Chapter 25, Problem 1CQ
To determine
Why two waves of significantly different frequencies cannot be coherent.
Expert Solution & Answer
Answer to Problem 1CQ
The phase relationship is not present with waves of different frequencies, so they cannot be coherent.
Explanation of Solution
The coherent waves will have a definite fixed phase relationship between them. If the frequency of the waves are somewhat identical, there will be a slight phase matching between the waves, and they can be coherent.
The waves given here have very significant difference in their frequencies. This will ensure that the waves will not be coherent. Therefore, the waves of different frequencies do not have phase relationship, they cannot be coherent.

The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. Find the direction of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane.
Give a more general expression for the magnitude of the torque τ. Rewrite the answer found in Part A in terms of the magnitude of the magnetic dipole moment of the current loop m. Define the angle between the vector perpendicular to the plane of the coil and the magnetic field to be ϕ, noting that this angle is the complement of angle θ in Part A.
Give your answer in terms of the magnetic moment mm, magnetic field B, and ϕ.
