Angle of Incidence Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle of Incidence = Angle of Deviation+Angle of Prism-Angle of Emergence
i = D+A-e
This formula uses 4 Variables

Variables Used

Angle of Incidence - (Measured in Radian) - Angle of Incidence is the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.
Angle of Deviation - (Measured in Radian) - Angle of Deviation is the angle between the incident ray and the path of the refracted ray.
Angle of Prism - (Measured in Radian) - Angle of Prism is the angle between the prism between two lateral surfaces.
Angle of Emergence - (Measured in Radian) - Angle of Emergence is the angle between the incident ray and the path of the emergent ray.

STEP 1: Convert Input(s) to Base Unit

Angle of Deviation: 12.5 Degree --> 0.21816615649925 Radian (Check conversion here)
Angle of Prism: 35 Degree --> 0.610865238197901 Radian (Check conversion here)
Angle of Emergence: 4 Degree --> 0.0698131700797601 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

i = D+A-e --> 0.21816615649925+0.610865238197901-0.0698131700797601

Evaluating ... ...

i = 0.759218224617391

STEP 3: Convert Result to Output's Unit

0.759218224617391 Radian -->43.5 Degree (Check conversion here)

Power of Lens using Distance Rule

Go Power of Lens = Power of First Lens+Power of Second Lens-Width of Lens*Power of First Lens*Power of Second Lens

Angle of Deviation

Go Angle of Deviation = Angle of Incidence+Angle of Emergence-Angle of Prism

Angle of Emergence

Go Angle of Emergence = Angle of Prism+Angle of Deviation-Angle of Incidence

Angle of Incidence

Go Angle of Incidence = Angle of Deviation+Angle of Prism-Angle of Emergence

Angle of Prism

Go Angle of Prism = Angle of Incidence+Angle of Emergence-Angle of Deviation

Angle of Deviation in Dispersion

Go Angle of Deviation = (Coefficient of Refraction-1)*Angle of Prism

Number of Images in Kaleidoscope

Go Number of Images = ((2*pi)/Angle between Mirrors)-1
