J Write down an expression for the highest order m of diffraction in a double slit experiment if the distance between the slits is a and slits are illuminated with light of the wavelength A. Please use "*" (without the quotes) for products (e.g. B*A), "/" for ratios (e.g. B/A) and the usual "+" and "- "signs as appropriate. For exponents (e.g. A²) use A*A or A^2 notation: thus A³/B should appear as either A*A*A/B or A^3/B. For greek letters use "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin" (without the quotes). Thus for Acoso use A*ços theta.
