What's the Difference Between Cold and Hot Transitions of Light?

AI Thread Summary
Hot transitions of light occur when energy absorption leads to increased atomic vibrations and physical changes, such as sunburn from UV exposure or food heating in a microwave. In contrast, cold transitions involve light absorption that facilitates chemical processes without generating heat, like photosynthesis in plants or neural impulses in the eye. The distinction lies in the energy transformation, with hot transitions resulting in thermal effects and cold transitions focusing on chemical or biological reactions. Understanding these differences is crucial in fields like photochemistry and biology. The discussion highlights the significance of energy absorption mechanisms in various contexts.

Can someone briefly explain the definition or the difference between a cold and hot transition of light?

Hot transition involves a change in an atoms vibration and standing wave patterns from absorbtion of higher frequency, such as skin sunburn from long exposures to ultraviolet light or physical change in food from microwave.

What are some examples and the process of cold transitions?

When light is absorbed by a leaf or some other green life, the energy is used to make chemical bonds and not heat. Also when light is absorbed in the eye, it causes neural impulses.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
