Dispersion of light and temperature

AI Thread Summary
The discussion centers on the dispersion of light using an equilateral prism and the temperature readings from three thermometers placed above red, green, and violet light. The highest temperature is expected above the red light due to the presence of infrared radiation, which contributes to increased heat. A second reason for the higher temperature could be the lower energy of red light compared to violet, leading to less energy dissipation in the form of heat. The original poster expresses doubt about the validity of the question due to a lack of responses despite significant views. The inquiry remains unresolved, highlighting a need for clarification on the topic.

In a question about dispersion using an equilateral prism, three blackened bulb thermometers were used. One was placed above the red light, one on the green light and the last one below the violet light.

The question was ...

Give 2 reasons why the highest temperature would be recorded above the red light.

My guess is...

Reason 1: There is the presence of infrared radiation which causes a temperature increase.
Reason 2: ?


Any help please?

Regards.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
