Answer 1

Here is the answer of above question (see below for details):

Answer: Option (f) 2.07 E4

X-Ray freequency (f) = er -19 Where e=1.6 x 10" V = ? h = 6+63 1834 x- may wave length (A) = ? c = 3x108 m/s mm 60.0pm = 6x10 m va exh 3x108 x 6.63 x 1034 = 20718.75 = 2.07 x16" or 2. 0764 Answer / optien (f)
