    Photons Surface
AI Thread Summary
To calculate the number of photons absorbed by a surface when light with a frequency of 4.41*10^15 Hz impinges on it, use the formula E = hf to determine the energy of each photon. Given that the surface gains 1.13*10^-16 J of energy, divide this total energy by the energy of a single photon to find the number of photons absorbed. This approach effectively utilizes the relationship between energy, frequency, and the Planck constant. The calculation is straightforward once the energy per photon is established. Understanding these principles is essential for accurate photon absorption calculations.

If light with a frequency of 4.41*10^15 Hz falls on a surface that gains 1.13*10^-16 J of energy, how many photons has the surface absorbed?



Probably simple, I've been using E = hf and such, but I got no idea from there



Help meeee please
 
Physics news on Phys.org
since you have the frequency of the light, you can calculate the energy of each photon with E = hf. with the energy of each photon and the total energy the surface has absorbed, you can calculate the number of photons by dividing the total energy by the energy of an individual photon.
 
Excellent, thankyou very much
 

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...
