Questions 3 (24) 3.1 Define resolving power? (2) 3.2 Suppose the pupil of falcon's eye has a diameter of 6.0 mm. Two chicks are separated by a distance of 0.010 m. From a distance of 156 m, the falcon sees them as one unresolved object and dives toward them at a speed of 15 m/s. Assume that the falcon's eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the chicks as separate objects? (6) 3.3 A diffraction grating is 3.00 cm wide and contains 11500 lines when used with light of a certain wavelength, a third order principal maximum is formed at an angle of 48.6. What is the wavelength (in nm)? 3.4 A ray of light strikes material (A) at an incident angle of 22.0' and refract at an angle of 13.7, as shown in the figure below. What is the speed of light (in m/s) in material (A)? Air Material (A) 1 A convex mirror has a radius of curvature of 26.0 cm. An object with a diameter of 8.00 cm is placed 60.0 cm from the mirror. Determine: (a) the object 's image position (3) (b) the object 's image diameter (3) (c) any two properties of the object 's image (2)
