1.	The wavelengthrangeof the visiblespectrumextendsfromvloler(400nm)to red(750nm)Expressthesewavelengthin frequency(Hz)
Answer» SOLUTION :forultravioler 400nm= 400 `xx 10^(9)m= lambda` C=velocityof lightin VACUUM= 30.`xx10^(8) ms^(-1)` `v=(c )/(lambda) = (3.00xx 10^(8)ms^(-1))/(400 xx 10^(9)m)` Wavelength`= lambda= 750nm = 750xx 10^(9) m` and v=c= 30`xx 10^(8)ms^(-1)` `v=(c )/(lambda )= (3.0xx 10^(8) ms^(-1))/(750 xx 10^(9 ) m)` Therangeof visiblespectrumis from `40xx 10^(14)` hz to7.5 `xx 10^(14) Hz`in terms offrequecny units.
