Give reason that ultrasonics not be produced by passing high frequency alternating current by a loud speaker
At these high frequencies, inductive reactance is so high where is no current flows throughout the coil of the loud speaker and therefore ultrasonic waves cannot be produced.
Suppose Fluid (say, water) occupies a domain D and has velocity field V=V(x, t). A substance (say, a day) is suspended into the fluid and will be transported by the fluid as well
Define the characteristics of Heterojunction laser. Heterojunction laser: The threshold current density for homojunction lasers is extremely large because of poor optical an
