Angular Width of Central Maxima Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angular Width = (2*Wavelength)/Aperture of Objective
d_angular = (2*λ)/a
This formula uses 3 Variables

Variables Used

Angular Width - (Measured in Radian) - Angular Width is the angle between the two extreme points of a wave measured at a reference point, typically the center of the wave, and is used to describe the spatial extent of a wave.
Wavelength - (Measured in Meter) - Wavelength is the distance between two consecutive peaks or troughs of a wave, which is a fundamental property of a wave that characterizes its spatial periodicity.
Aperture of Objective - Aperture of Objective is the diameter of the objective lens that determines the amount of light that enters the microscope, affecting the resolution and quality of the resulting image.

STEP 1: Convert Input(s) to Base Unit

Wavelength: 26.8 Centimeter --> 0.268 Meter (Check conversion here)
Aperture of Objective: 5.11 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_angular = (2*λ)/a --> (2*0.268)/5.11

Evaluating ... ...

d_angular = 0.104892367906067

STEP 3: Convert Result to Output's Unit

0.104892367906067 Radian -->6.00988998415223 Degree (Check conversion here)

FINAL ANSWER

6.00988998415223 ≈ 6.00989 Degree <-- Angular Width

What is Fraunhoffer Diffraction?

Fraunhofer Diffraction occurs when light passes through a small aperture or around an edge and the observer is at a large distance from the aperture. It results in a pattern of light and dark regions due to the interference of light waves. This type of diffraction is analyzed with parallel light waves and produces a distinct, predictable pattern.

How to Calculate Angular Width of Central Maxima?

Angular Width of Central Maxima calculator uses Angular Width = (2*Wavelength)/Aperture of Objective to calculate the Angular Width, Angular Width of Central Maxima formula is defined as the angle subtended by the central maximum at a distance from the slit, which is a measure of the diffraction pattern's central maximum width in an optical setup, characterizing the spread of light around the central peak. Angular Width is denoted by d_angular symbol.
