Every one of us uses the camera to click photographs, we use sunglasses when we walk out of our house during daytime, also in our car, we have a mirror of a film. Let's learn, practice, and master topics of class 11 physics (NCERT) starting with kinematics and then moving to dynamics with Newton's laws of motion, work, energy, and power. There are three types of waves. If Vs, Vi and Vg are speed of sound waves in solid, liquid and gases, then, Sound waves (longitudinal waves) can reflect, refract, interfere and diffract but cannot be polarised as only transverse waves can polarised. Beats. (ii) Longitudinal waves A wave in which the particles of the medium vibrate in the same direction in which wave is propagating, is called a longitudinal wave. Learn the fundamentals of waves and sound in this unit. Therefore, velocity of longitudinal (sound) waves in gas should be. These are the Waves class 11 Notes Physics prepared by team of expert teachers. For this situation, the approach frequency is. Also, students will get well worse with the questions of this chapter.

Project Report on Semiconductor. When two waves of same frequency travel in a medium simultaneously in the same direction, then due to their superposition, the resultant intensity at any point of the medium is different from the sum intensities of the two waves. The velocity of sound in a gas is inversely proportional to the square root of density of the gas. Electromagnetic Waves Those waves which do not require a material medium for their propagation, are called electromagnetic waves, e.g., light waves, radio waves etc. Such a body leaves behind it a conical “egion of disturbance which spreads continuously. The minimum distance from a sound reflecting surface to hear an echo is 16.5 m. If first echo be heard after It second, second echo after ~ second, then third echo will be heard after (t1 + t2)s. Two or more progressive waves can travel simultaneously in the medium without effecting the motion of one another. It is the sound of lowest frequency produced in fundamental note., vibration of a system.
