What is the Bunsen Roscoe Law of Reciprocity

The intensity and duration of the dose of radiant energy are inversely proportional

32

What is the equation for the Bunsen Roscoe Law of Reciprocity

Energy=intensity*time

33

True or False:
The greater the temperature differential the quicker the transfer of energy

True

34

How do you increase the amount of energy absorbed by the patient (4)

1. Increase treatment time
2. Increase treatment intensity
3. Lessen the distance of the source of energy
4 Make the source of energy more perpendicular to the absorbing surface
