QAIPMT-2010-Ph-2046: NEET 2010 Physics - Class 12 AIPMT-2010-Ph-2046 Solution: A tuning fork of frequency 512 Hz makes 4 beats per second with …
A tuning fork of frequency 512 Hz makes 4 beats per second with the vibrating string of a piano. The beat frequency decreases to 2 beats per sec when the tension in the piano string is slightly increased. The frequency of the piano string before increasing the tension was 510 Hz 514 Hz 516 Hz 508 Hz
Multiple Choice Options
- A Both electric and magnetic field vectors attain the maxima and minima at the same place and same time.
- B The energy in electromagnetic wave is divided equally between electric and magnetic vectors.
- C Both electric and magnetic field vectors are parallel to each other and perpendicular to the direction of propagation of wave.
- D These waves do not require any material medium for propagation.
Step-by-Step Verified Solution
