Explanation:

Molecular wight of NaOH=23+16+1=40

The molarity of NaOH solution is

M=

Mw

2

×V

sol

W

2

×1000

=

40×100

4×1000

=1 M.

Since, NaOH is monobasic acid its normality and molarity will be same.

Hence, the normality of NaOH solution is 1 N.

Thus, there is no difference in the normality and molarity of NaOH solution.

Suppose pure-wavelength light falls on a diffraction grating. What happens to the interference pattern if the same light falls on a grating that has more lines per centimetre? What happens to the interference pattern if a longer-wavelength light falls on the same grating? Explain how these two effects are consistent in terms of the relationship of wavelength to the distance between slits.
