Power of Lens using Distance Rule Solution

STEP 0: Pre-Calculation Summary
Formula Used
Power of Lens = Power of First Lens+Power of Second Lens-Width of Lens*Power of First Lens*Power of Second Lens
P = P1+P2-w*P1*P2
This formula uses 4 Variables
Variables Used
Power of Lens - Power of Lens is a measure of deviation produced by it in the path of rays refracted through it. Its unit is Dioptre (D).
Power of First Lens - Power of First Lens we define power of lens as the reciprocal of the focal length of the lens used.
Power of Second Lens - Power of Second Lens we define power of lens as the reciprocal of the focal length of the lens used.
Width of Lens - (Measured in Meter) - Width of Lens is the measurement or extent of lens from side to side.
STEP 1: Convert Input(s) to Base Unit
Power of First Lens: 0.75 --> No Conversion Required
Power of Second Lens: 1.25 --> No Conversion Required
Width of Lens: 0.2 Meter --> 0.2 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
P = P1+P2-w*P1*P2 --> 0.75+1.25-0.2*0.75*1.25
Evaluating ... ...
P = 1.8125
STEP 3: Convert Result to Output's Unit
1.8125 --> No Conversion Required
FINAL ANSWER
1.8125 <-- Power of Lens
(Calculation completed in 00.006 seconds)

8 Basics of Optics Calculators

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
Power of Lens
Go Power of First Lens = 1/Focal Length 1
