Role of Magnetic field in generating ultrasonic waves
Magnetic field is applied parallel to the length of a ferromagnetic rod made of material as like iron or nickel, a small elongation or contraction arises in its length. It is termed as magnetostriction. The change into length depends onto the intensity of the applied magnetic field and nature of the ferromagnetic material. The change within length is independent of the direction of the field.
Presume that you are asked to find the image position in a problem involving a lens. You are specified the object position and you are told that the lens is a concave lens whose fo
A wave is a disturbance which transmits power and momentum from one place to the other without the transport of matter.
