Explanation Given info: The distance from the source is tripled. Formula to calculate the speed of the sound is, v = f λ Here, λ is the wavelength. f is the frequency. v is the speed of the sound. The speed of the sound in air at atmospheric pressure is determined by the temperature of the air and does not depend on the frequency of the sound if both are same medium, whatever high be the frequency of the source and both will have same speed. Conclusion: The speed of the sound from B is twice as fast if speed of the sound of B directly proportion to the frequency of A , which is contradictory. Thus, option (a) is not correct

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.
