Two sitarstrings A and B playing the note ‘Ga’ are slightly out of tune and produce beats of frequency 6 Hz. The tension in the string A is slightly reduced and the beat frequency isfound to reduce to 3 Hz. If the original frequency of A is 324 Hz, what is the frequency of B?

Photoelectric effect When light of sufficeintly small wavelength is incident on a metal cathode, it may emit electons called photoelectrons. Above threshold frequency the stopping potenital and hence the energy of the photoelectrons are directly proportional to the frequency. in the given figure, we see the variation of stopping potential with the frequency of incident radiation for three metals A, B and C. Slope of graph is given by

The blood groups of 30 students of Class VIII are recorded as follows: A, B, O, O, AB, O, A, O, B, A, O, B, A, O, O, A, AB, O, A, A, O, O, AB, B, A, O, B, A, B, O. Represent this data in the form of a frequency distribution table. Which is the most common, and which is the rarest, blood group among these students?

The amgnetic field in a plane electrmagnetic wave is given by B_y = 2 xx 10^(-7) sin [0.5 xx 10^3 x + 1.5 xx 10^(11) t]] (in T) What is the waelength and frequency of the wave?
