Two light bulbs are 1.20 m apart. From what distance can these light bulbs be marginally resolved by a small telescope with a 3.70 cm -diameter objective lens? You may want to review (Pages 1011 - 1014) Part A Assume that the lens is diffraction limited and A = 600 nm. Express your answer with the appropriate units. HẢ Value Units

A diffraction grating with n = 2.5E-05 lines/nm is used to separate two colors of light. The angle between their first maxima is Δθ ≡ θ1 - θ2 = 0.44 degrees, and the first light has wavelength λ1 = 618 nm.  Part (a)  Find θ1 using n and λ1 in radians.   Part (b)  Find θ2 in radians.  Part (c)  Find the value of the wavelength of the second color λ2 in nm.
