Explain the basic concept of sonar.
Basic concept of SONAR:
Sonar is based ontpo the echo-sounding technique of ultrasound. While an ultrasonic wave is transmitted by water, this is reflected through the objects into the water and will generate an echo signal. By considering the time interval among the generation of the ultrasonic pulse and the reception of the echo signal (t), the depth of the object can be simply computed. As the ultrasonic velocity “v’ into sea water is termed, the depth of sea is computed as given below:
Depth of sea (distance in between surface and bottom of the sea) = vt/2
Similar procedure is also used to determine the distance of submarine or iceberg through the surface of the sea and the distance in between two ships into the sea.
A 5.0-cm-tall object is placed 16 cm from a convex lens with a focal length of 8.4 cm. What are the image height and orientation?
Sliding versus Static Friction: Friction force is the force exert by a surface as an object moves crosswise it or makes an effort to move across it. Two types of friction force

Start by opening the "Maze Game" activity. When you open it you will be presented with the "Arena of Pain". Set it to "practice" and play with the controls. You will find that by c
What is splicing? Splicing: Two optical fibers utilized for communication are joined with a process termed as Splicing. This must be done very carefully that is the splicing
It is the property of a material by virtue of which it allows itself to be magnetized. Permeability varies from material to material depending upon the saturation and temperature.
Q. A prism is made of glass of unknown refractive index. A parallel beam of light is incident on a face of the prism. The angle of minimum deviation is measured to be 40°.What is t
