Structure Of Atom

Question
CBSEENCH11005241
Wired Faculty App

Calculate the wavelength, frequency and wave number of light wave whose period is 2.0 x 10-10 s

Solution

Here,   straight T space equals space 2.0 space cross times space 10 to the power of negative 10 end exponent straight s
Frequency space left parenthesis straight v right parenthesis space equals space 1 over straight T space equals fraction numerator 1 over denominator 2.0 space cross times space 10 to the power of negative 10 end exponent straight s end fraction space space space space space space space space space space space space space space space space space space space space space equals space 5.0 space cross times space 10 to the power of negative 9 end exponent straight s to the power of negative 1 end exponent
Wavelength left parenthesis straight lambda right parenthesis space equals space straight c over straight v space equals fraction numerator 3 space cross times space 10 to the power of 8 space ms to the power of negative 1 end exponent over denominator 5.0 space cross times 10 to the power of 9 space straight s to the power of negative 1 end exponent end fraction
                   equals space 6.0 space cross times space 10 to the power of negative 2 end exponent space straight m
W a v e space n u m b e r space left parenthesis straight v with bar on top right parenthesis space equals space 1 over straight lambda equals space fraction numerator 1 over denominator 6.0 space cross times 10 to the power of negative 2 end exponent straight m end fraction space equals 16.66 space straight m to the power of negative 1 end exponent
