Given that the cumulative frequencies of less than type and more than type corresponding to a class interval are 320 and 323 respectively, when the total frequency is 500, find the percentage of the class-interval.

Statement I: Any light wave having frequency less than 4.8 xx 10^(14)Hz cannot emit photoelectrons from a metal surface having work function 2.0 eV Statement II: If the work function of a metal is W_(0) (in eV), then the maximum wavelength (in Å ) of the light capable of initiating photoelectric effect in the metal is given by lamda_("max") = (12400)/(W_(0))

If f_i, F_i, F'_i are respectively the frequency less than type cumulative frequency, greater than type cumulative frequency of i-th class and N be the total freqnency then which of the following is correct?

Name the electromagnetic waves that have frequencies greater than those of ultraviolet light but less than those of gamma rays.

Make a cumulative frequency (less than type) table and draw a o give from the give data.

The length of a dipole antenna for the carrier wave of frequency 3 xx 10^8 Hz will be—
