A double-slit diffraction pattern is formed on a distant screen. If the separation between the slits decreases, what happens to the distance between interference fringes? Assume the angles involved remain small. The distance between interference fringes remains the same. The effect cannot be determined unless the distance between the slits and the screen is known. The distance between interference fringes also decreases. The distance between interference fringes increases.

When red light (λr = 715 nm) illuminates a diﬀraction grating, a second order maximum is seen at a vertical location y = 12.5 cm on a screen L = 45.0 cm away from the grating. (a) At what angle does the second order maximum occur? (b) What is the distance, d, between the slits? (c) If the grating is 2.50 cm wide, how many slits make up the grating? (d) Where on the screen would the second order maximum...

i) Find the angular separation between the red hydrogen-α spectral line at 656 nm and the yellow sodium line at 589 nm if the two lines are observed in third order with a diffraction grating having 3 500 slits per cm. (Give the answer in degrees, correct to three significant figures.) [6] (ii) Using the same diffraction grating as in (i) , what is the highest order that could possibly be observed using violet light of wavelength 420 nm?

A diffraction grating has a chromatic resolving power of 20,000 in first order (m = 1). (i) What is the number of slits in the grating? (ii) This grating is used to analyze the spectrum of light coming from stars, in the third order (m = 3). The analysis involves resolving wavelengths that are close the spectral wavelength of some element (500.0 nm). What is the range of wavelengths you cannot distinguish from the said spectral wavelength? Hint: Chromatic resolving...

A student is studying a reaction between reactants A and B. the reaction is second order with respect to A, but zero order with respect to B. Explain in 5-6 sentences what this means. If the Concetration of A is tripled what will the effect be on the reaction rate? If the concentration of B is increased 10 times, what will the effect be on the reaction rate?
