Answer:

2√109 about 20.88

Explanation:

The mean of this set of numbers is (75+83+96+100+121+125)/6 is 100. Next step is ((75-100)^2+(83-100)^2+(96-100)^2+(100-100)^2+(121-100)^2+(125-100)^2)/6 this result is called deviation. Square root the deviation(436) then you set the standard deviation.

An oil film (n = 1.48) of thickness 290 nm floating on water is illuminated with white light at normal incidence. What is the wa
jasenka [17]

Answer:

The correct option is  D

Explanation:

From the question we are told that

   The  refractive index of oil film is k =  1.48

   The  thickness is t =  290 \ nm  =  290*10^{-9} \ m

   

Generally for constructive interference

      2t  =  [m  + \frac{1}{2} ]*  \frac{\lambda}{k}

For reflection of a bright fringe m =  1

 =>   2 * (290*10^{-9})  =  [1  + \frac{1}{2} ]*  \frac{\lambda}{1.48}

=>     \lambda  =  5.723 *10^{-7} \  m

This wavelength fall in the range of a yellow light
