One simple experiment that you can do would involve a dry cell battery, an LED, connecting wires, a breadboard, and a 220 ohm resistor. Connect all of the components in series. Using a multimeter, measure the resistance and the current across the LED.

g When the movable mirror of the Michelson interferometer is moved a small distance X while making a measurement, 246 fringes ar

zhenek [66]

Answer:

X = 69.1 x 10⁻⁶ m = 69.1 μm

Explanation:

The relationship between the motion of the moveable mirror and the fringe count of the Michelson's Interferometer is given by the following formula:

d = mλ/2

where,

d = distance moved by the mirror = X = ?

m = No. of Fringes counted = 246

λ = wavelength of light entering interferometer = 562 nm = 5.62 x 10⁻⁷ m

Therefore,

X = (246)(5.62 x 10⁻⁷ m)/2

Therefore,

X = 69.1 x 10⁻⁶ m = 69.1 μm
