Problem
Standing waves can be formed by reflecting light from a mirror and allowing the reflected light to interfere with the incident light. Suppose that we do so using light with a wavelength of 600 nm (6.00 x 10 -7 m). Assume that there is a node at the mirror.
i. How far from the mirror will we encounter the first antinode?
ii. What is the separation of adjacent antinodes as we move away from the mirror?
