Write down an expression for the angle of the first minimum of diffraction of light of wavelength A by a circular aperture of diameter d. Please use appropriate algebraic symbols for multiplication (* for a × b), division (/ for a/b), exponents (a^b for a³), square root (sqrt(a*b/c) for √a × b/c) etc. For Greek letters use their names e.g. "theta" (without the quotes) and for trigonometric functions use "cos", "tan", "sin", "asin" (for arc sine etc., without the quotes). Thus for Acose use A* cos theta or for A*sin‍¹ (a+b) use A*asin(a+b) etc. Please use the "Display response" button to check you entered the answer you expect. 0= Display response
