illuminated of a light of frequency 1.3 x
10'S Hz the maximum energy of photo
electron it to be 1.8eV. Evaluate the
threshold frequency and the threshold
wavelength.

the answer is a. hope this .

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.
