Reflexion and transmission in case of heating

In summary, the conversation discusses the effects of a laser beam polarized arriving from vacuum to a medium, specifically the reflection and transmission powers taking into account heating. The question is raised about what equations can be used to solve this, specifically how the reflection coefficients may depend on temperature and how to compute the absorbed power due to heating. The medium in question is from air to glass.

Suppose a laser beam polarized arriving from vacuum to a medium. What are the reflexion and transmission powers taking into account heating. What equations could be used to solve this ?

It is unclear what are you asking here. Heating what?
You mean to ask how (or if) the reflection coefficients depend on temperature?
 
  • #3
Yes, the beam heats the medium up and this will modify the reflected and transmitted intensities.
 
  • #4
It may be just that the beam damages (changes) the quality of the surface and by this changes the amount of light reflected.
What is this medium?
 
  • #5
From air to glass for example. I was wondering how to compute the absorbed power due to heating.
 

1. What is the difference between reflection and transmission when it comes to heating?

Reflection is the process by which heat is bounced off a surface without being absorbed, while transmission is when heat passes through a material and is absorbed.

2. How do reflection and transmission affect the temperature of a material?

Reflection can cause a material to maintain its temperature, while transmission can increase the overall temperature of the material as it absorbs heat.

3. Can reflection and transmission be controlled or manipulated?

Yes, reflection and transmission can be controlled through the use of different materials and surfaces that are designed to either reflect or absorb heat. These properties can also be altered by changing the angle or intensity of the heat source.

4. Does the color of a material affect its reflection and transmission properties?

Yes, the color of a material can affect how much heat is reflected or transmitted. Darker colors tend to absorb more heat, while lighter colors reflect more heat.

5. How do environmental factors, such as humidity, affect reflection and transmission in heating?

Humidity can play a role in how heat is reflected and transmitted. Higher levels of humidity can increase the amount of heat absorbed by a material, while lower levels of humidity can increase the amount of heat reflected.
