Nichols and Hull Experiment (Radiation pressure).
Q: The calculated uncertainty in their measured value, 7.01 μPa of the pressure of light was 1.5%. Discuss briefly whether or not the result of their experiment confirms the theory of radiation pressure.
Thanks in advance!

This does show radiation pressure

anonymous · Answer

Where all those question marks are, it's suppose to be $$\mu Pa$$

paxpolaris · Answer

the fact that the pressure was only measured to 7.01 micro Pascals doesn't matter.

since uncertainty is only $1.5\%$  the radiation pressure has to be between $6.90$ and $7.12\ \mu Pa$


the only way the experiment would not confirm the theory is ... with around $100\%$ uncertainty

Thank you! Can you help me with 1 more question please?

Here it is:
Consider the following argument:
The momentum transferred to a surface= I At.
Hence the force exerted on the surface = I A/c ---> Step 1.
Hence the pressure on the surface= I/c ---> Step 2.
Q: State the physical principle used in step 1 and in step 2.
