Agamma ray with wavelength 1.0 x 1013 meters is passing through empty space. (a) what is the frequency of this gamma ray? ytravel from the sun to jupiter(adistance of 7.8 x 108 km)? 21 suppose that you are viewing a very pure green light. (a) in order to make it appear a very pure red light, one would (select one choice from each set): (increase/decrease) the light wave's (amplitude/frequency/saturation) (b) in order to make it appear a less pure green color (a pastel green for example), one would: (increase/decrease) the light wave's (amplitude/frequency/saturation)

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?
