1)
Answer: e )7.30 x 10^14 Hz
f = c / lambda
where
f=frequency
c = speed of light = 3x 10^8 m/s
lambda = 411 nm = 411x 10^(-9) m
Therefore f = c / lambda =(3x 10^8 m/s )/ 411x 10^(-9) m= 7.30 x 10^14 Hz
2)
Answer: e 8.27 x 10^5 Joules
E=h nu
Where
E= energy of photon
h=Planck's constant= 6.63x10^(-34) joule-sec
nu = frequency=6.91x10^14 Hz
Therefore E=h nu = 6.63x10^(-34) joule-sec x 6.91x10^14 ...
