Homework Statement


I've linked my data table down below. My problem is the relative intensity column. From the table, the units of relative intensity are w/m/s. I'm assuming this is power/velocity, where velocity is the speed of light. However, nowhere in the lab manual did it mention the power. So I was wondering whether there is a way to determine power, or perhaps an alternative approach. I'm fairly certain I did not miss any data collection steps. So any guidance here would be greatly appreciated.

Homework Equations


c = λv

The Attempt at a Solution


Relative Intensity = Power/Velocity?

Relative Intensity = Power/Velocity?
Power / velocity makes no sense in this context. W/m/s looks like a typo. If they really meant that it should be written Ws/m.
Relative intensity is not a well-defined term. The obvious interpretation would make it simply a ratio, such as a fraction of the total power. In that case it would be dimensionless.
If the context is perception, it might mean perceived brightness.
In some contexts the s could be a reference to steradians rather than seconds, but the W/m/s formula still makes no sense.
