Acharge of 1.5 × 1015 coulombs moves from point a to a lower potential at point b. the electric field is uniform at 2.5 × 10-5 newtons/coulomb and the distance along the field lines between the two points is 1.7 × 10-2 meters. what is the work done? 1.5 × 10-12 joules

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?

Although light from the sun appears white, it is actually made up of a lot of different colors. this portion of the electromagnetic spectrum, we call white light is referred to as within the electromagnetic spectrum.
