The medium wave(MW) band coresponds to wavelength range 200 m to 625 m.If a radio can tune to any station in this and,what is the corresponding frequency band?

A radio can tune in to any station in the 7.5 MHz to 12 MHz band. What is the corresponding wavelength band?

A person has a hearing range from 20 Hz to 20 KHz. What is the typical wavelength of sound waves in air corresponding to these frequencies ? Take the speed of sound in air as 344 ms^ -1 .

A wave moves a distance of 8 m in 0.05 s. What is the wavelength of the wave if its frequency is 200 Hz?

The transvers displacement of a string (clamped at its both ends) is given by y(x,t) = 0.06 sin ((2pi)/(3)s) cos (120 pit) Where x and y are in m and t in s. The length of the string 1.5 m and its mass is 3.0 xx 10^(-2) kg. Interpret the wave as a superposition of two waves travelling in opposite directions. What is the wavelength, frequency, and speed of each wave ?

A radio can tune over the frequency range of a portion of MW broadcast band: (800 kHz to 1200 kHz). If its LC circuit has an effective inductance of 200 muH , what must be the range of its variable capacitor?

A train, standing in a station-yard, blows a whistle of frequency 400 Hz in still air. The wind starts blowing in the direction from the yard to the station with a speed of 10 m s^-1 . What are the frequency, wavelength, and speed of sound for an observer standing on the station’s platform? Is the situation exactly identical to the case when the air is still and the observer runstowards the yard at a speed of 10 m s^-1 ? The speed of sound in still air can be taken as 340 m s ^-1 .
