Which Electromagnetic Radiation Has the Greatest Photon Energy?

AI Thread Summary
X-rays are identified as the electromagnetic radiation most easily observed through Compton scattering from electrons. In terms of photon energy, X-rays also have the highest energy compared to blue light, microwaves, and radio waves. The relationship between photon energy and wavelength is crucial, as shorter wavelengths correspond to higher energy. Participants are encouraged to explore the reasoning behind these concepts rather than simply providing answers. Understanding the physics behind these phenomena is the main goal of the discussion.

1. Compton scattering from electrons is most easily observed for:

*microwaves *infrared light *visible light *ultraviolet light *x rays

I Think it refer to x ray . but not sure what do you think guyz .. please tell me if you can

2.Which of the following electromagnetic radiations has photons with the greatest energy?

*blue light * microwave * x ray * radio wave * yellow light

as far as i think its radio wave what do you say about this .. THank you

Well how have you reasoned?

For the first, Q do you have a formula for the change in wavelength/frequency for scattered photons?

For the second Q, what is the relation between photon energy and wavelenght of the EM-wave? How would you order the alternatives you've got with respect to increasing wave lenght?

(I will not just give you the answers, I want you also to be able to see WHY they are the right answers, that is the purpose of physics forum)
 

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...
