Red Light Energy Formula
The following equation is used to calculate the Red Light Energy.
E = h*fr
Variables:
- Where E is the Red Light Energy (Joules)
- fr is the frequency of the red light (hz)
- h is the Planck’s Constant (6.626 * 10 ^-34 J-s)
How to Calculate Red Light Energy?
The following two example problems outline the steps and information needed in order to calculate the Red Light Energy.
Example Problem #1:
- First, determine the frequency of the red light (hz). In this example, the frequency of the red light (hz) is measured to be 40000.
- Finally, calculate the Red Light Energy using the formula above:
E = h*fr
Inserting the values from above and solving the equation with the imputed values gives:
E = 6.626 * 10 ^-34*40000 = 2.65e-29 (Joules)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
frequency of the red light (hz) = 2000
Entering these values into the formula or calculator above gives us:
E = 6.626 * 10 ^-34*2000 = 1.3252e-30 (Joules)
