10. What is photobiomodulation and how does it differ from LLLT?

11. Be able to explain because you understand these studies

Explanation / Answer

#1

Photodynamics laws says that momentum given by the photons is always in the direction of incident photons

#2

Radiance is the radiated waves, irradiance is the waves incident upon it

#3

Continuouc current can give continuous waves so it is better to achieve continuous photons

#4

Joule in mW means the power which is radiated by given amount in per unit time
