D- Ultrasonic wave Heating
These waves are different from electromagnetic waves . It produces mechanical vibration inside tissue. It is the same as the sound waves but it has much higher frequencies about I MHz with power of several watts per centimeter. It can move the tissue particles backward and forward with high frequency, in doing so it can increase the kinetic energy consequently it heats the tissue.
Ultrasound can be produced by special transducers placed in direct contact with the skin. It is used for relieving tightness and scarring occurring in jointdisease. It can dispose more heat in bones, as bones are better absorber for ultrasonic energy than soft tissue. It is also used in deep therapy.
Write down the expression for the equivalent focal length of two thin lenses separated by a distance and illustrate the terms.
A box is divided into two parts of equal volume via a partition. The box is thermally insulated from the surroundings. Consider that compartment 1 contains an ideal gas A at P 0 ,
What is a P-N junction? How does it behave under forward and reverse bias? Describe with the help of circuit diagrams.
What are lens aberrations? Give reasons for them. Illustrate the working of a simple microscope and give a mathematical expression for its magnifying power.
The energy possessed by a object by virtue of its position or its configuration is called its potential energy. Concept of potential energy is valid only in conservative field.
