Answer:
d = 1.55 * 10⁻⁶ m
Explanation:
To calculate the distance between the adjacent grooves of the CD, use the formula, ..........(1)
The fringe number, m = 1 since it is a first order maximum
The wavelength of the green laser pointer, = 532 nm = 532 * 10⁻⁹ m
Distance between the central maximum and the first order maximum = 1.1 m
Distance between the screen and the CD = 3 m
= Angle between the incident light and the diffracted light
From the setup shown in the attachment, it is a right angled triangle in which
Putting all appropriate values into equation (1)
The resistance of a given conductor depends on its electrical resistivity (), its length(L) and its cross-sectional area (A), as follows:
In this case, we have ,
and
. So, the total resistance of the wire with length of 138m is:
