A В a) An ambulance moving with a speed of Vs m/s, produces a siren of frequency 544HZ, approaches an observer B, who is moving in the opposite direction with a speed of 26.45 m/s. If the frequency heard by the observer B is 608 Hz, and the speed of the sound is 332 m/s, calculate the Speed of the ambulance Vs, in m/s b) If now, the observer A is receding from the ambulance with the same speed as the observer B, calculate the

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.
