Alight ray just grazes the surface of the earth (m = 6.0 × 10 24 kg, r = 6.4×10 6 m). through what angle α is the light ray bent by gravitational lensing? (ignore the refractive effects of the earth’s atmosphere.) repeat your calculation for a white dwarf (m = 2.0 × 10 30 kg, r = 1.5 × 10 7 m) and for a neutron star (m = 3

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?
