Fringe Spacing given Apex Angle Solution

STEP 0: Pre-Calculation Summary

Formula Used

Fringe Space = Wavelength of Visible Light/(2*tan(Angle of Interference))
S_fri = λ_vis/(2*tan(α_opto))
This formula uses 1 Functions, 3 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Fringe Space - (Measured in Meter) - Fringe Space is defined as the distance between 2 fringes obtained during the Young's double slit experiment demonstrating interference of light waves.
Wavelength of Visible Light - (Measured in Meter) - Wavelength of Visible Light is the band of wavelengths in the range 400nm - 800nm of the electromagnetic spectrum that is visible to the human eye.
Angle of Interference - (Measured in Radian) - Angle Of Interference is the angle formed when the two light waves converge during interference.

STEP 1: Convert Input(s) to Base Unit

Wavelength of Visible Light: 500 Nanometer --> 5E-07 Meter (Check conversion here)
Angle of Interference: 10 Degree --> 0.1745329251994 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_fri = λ_vis/(2*tan(α_opto)) --> 5E-07/(2*tan(0.1745329251994))

Evaluating ... ...

S_fri = 1.4178204549047E-06

STEP 3: Convert Result to Output's Unit

1.4178204549047E-06 Meter -->1.4178204549047 Micron (Check conversion here)

FINAL ANSWER

1.4178204549047 ≈ 1.41782 Micron <-- Fringe Space
