Resultant Intensity On-Screen of YDSE when Intensities are Different Solution

STEP 0: Pre-Calculation Summary
Formula Used
Resultant Intensity = Intensity 1+Intensity 2+2*sqrt(Intensity 1*Intensity 2)*cos(Phase Difference)
I = I1+I2+2*sqrt(I1*I2)*cos(Φ)
This formula uses 2 Functions, 4 Variables
Functions Used
cos - Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle., cos(Angle)
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Resultant Intensity - (Measured in Candela) - Resultant Intensity is the resultant of two intensities combined together.
Intensity 1 - (Measured in Candela) - Intensity 1 is the quantity of energy the first wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed.
Intensity 2 - (Measured in Candela) - Intensity 2 is the quantity of energy the second wave conveys per unit time across a surface of unit area, and it is also equivalent to the energy density multiplied by the wave speed.
Phase Difference - (Measured in Radian) - Phase Difference is used to describe the difference in degrees or radians when two or more alternating quantities reach their maximum or zero values.
STEP 1: Convert Input(s) to Base Unit
Intensity 1: 9 Candela --> 9 Candela No Conversion Required
Intensity 2: 18 Candela --> 18 Candela No Conversion Required
Phase Difference: 38.5 Degree --> 0.67195176201769 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
I = I1+I2+2*sqrt(I1*I2)*cos(Φ) --> 9+18+2*sqrt(9*18)*cos(0.67195176201769)
Evaluating ... ...
I = 46.9219512500029
STEP 3: Convert Result to Output's Unit
46.9219512500029 Candela --> No Conversion Required
FINAL ANSWER
46.9219512500029 46.92195 Candela <-- Resultant Intensity
