What do Equations 1 and 2 predict will happen to the single-slit diffraction pattern (intensity, fringe width, and fringe spacing) as the slit width is increased. Equation 1:
Sinθ = mλ/ω

Equaiton 2:
I= Io [Sinθ (πωλ/πωλ/Rλ)

the firtz agrees with the expression for the shape of the curve of diracion of a slit

Explanation:

The diffraction phenomenon is described by the expression

              a sin θ = m λ

where a is the width of the slit, t is the angle from the center of the slit, l is the wavelength and m is an integer that corresponds to the maximum diffraction.

the previous equation qualitatively describes the curve of the diffraction phenomenon the equation takes the form

             I = I₀ [(sin ππ a y / R λ) / π a y / Rλ]²

             I = I₀ ’[sin π a y /Rλ]²

             I₀ ’= I₀ / (π a y /Rλ)²

By reviewing the two expressions given

equation 1

 w sin θ = m λ

where w =a  w   is the slit width

we see that the firtz agrees with the expression for the shape of the curve of diracion of a slit

Equation 2

the squares are missing

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
