Suppose that you had used an argon laser (wavelength=488 nm) instead of the HeNe laser. Calculate the width of the central maximum for the 0.04 mm slit assuming all other dimensions remain the same.
An object is located 13.5 cm in front of a convex mirror, the imagebeing 7.45 cm behind the mirror. A second object, twice as tall asthe first one, is placed in front of the mirror, but at a differentlocation. The image of this second object has t..
