Doppler Effect - Full explanation The Doppler Effect is the change in the frequency or wavelength of a wave as observed by someone moving relative to the source of the wave. In Simple Terms: When a source of sound (or light) moves towards you, the waves are compressed, you hear a higher pitch (higher frequency). When the source moves away, the waves are stretched, you hear a lower pitch (lower frequency). Common Example: Imagine an ambulance driving past you: • As it approaches, the siren sounds

Professor Walter Lewin’s explanation of angular momentum and torque often highlights their deep connection through Newton’s laws of motion. He explains that angular momentum, the rotational equivalent of linear momentum, depends on the moment of inertia and angular velocity of an object. Torque, on the other hand, is the rotational equivalent of force and causes a change in angular momentum. Using practical demonstrations, Lewin shows how torque applied at a distance from the pivot point creates
