What affects the intensity of different coloured lights?

AI Thread Summary
The discussion centers on an experiment measuring the light intensity of different colored plastics placed in front of a single light source. Results indicated that yellow, orange, and violet exhibited the highest light intensities, while red and green showed the lowest, with blue falling in between. Participants are exploring whether the observed intensity differences are influenced by the wavelength, frequency, or other factors. There is a focus on analyzing the relationship between intensity and frequency/wavelength through graphs. The type of light source used, such as incandescent or CFL, is also a point of inquiry for further understanding.

Okay, so I have completed a practical where I used a light box and then placed different coloured plastics in front of the light and measured the light intensity of each colour. From the results I found that yellow, orange and violet had the highest intensities, with red and green having the lowest intensity, with blue in the middle.

What made this happen? Does the wavelength of each colour change the intensity? or is it the frequency? or is it another factor?

If possible could someone please help! :)

There's just the one light source?
 
yes, there was only one light source
 
Have you plotted "intensity" versus frequency/wavelength?

Yeah that is the main graph that is being used for analysis

What do you know about the source? Incandescent filament? CFL? Something else?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
