<u>Answer:</u>
Frequency of orange light = 
Hz
<u>Explanation:</u>
We are given the wavelength of the orange light and we are to find the value of its frequency.
Wavelength of orange light = 
We know that:
Speed of light = Frequency of orange light × Wavelength of orange light
Substituting the values in the above formula:
= Frequency of orange light × 
Frequency of orange light = 
Hz
Well one of them is title waves...
The both have the unit (J) for Jules
