When a wave reflects off a higher index of refraction medium than the one it is traveling in, is the reflected wave aligned in the same or opposite orientation as the incident wave? When a wave reflects off a lower index of refraction medium than the one it is traveling in, is the reflected wave aligned in the same or opposite orientation as the incident wave? In the case where the alignment is flipped, what is the difference in wavelengths (N)? Scenario 1 Incident Wave (1) mm ww Reflected Wave (2) Lower Index of Refraction N = 1/2 Higher Index of Refraction Scenario 2 Incident Wave (1) m mw W Reflected Wave (2) Higher Index of Refraction N = 0 Lower Index of Refraction Examine the path for Ray 1 Does the light experience reflection? If so, Is the reflective surface a higher or lower index of refraction than where the ray was before/after reflection? Does the light experience transmission? If so, is the second medium a a higher or lower index of refraction than where the ray was before/after the transmission? Examine the path for Ray 2 Does the light experience reflection? If so, Is the reflective surface a higher or lower index of refraction than where the ray was before/after reflection? Does the light experience transmission? If so, is the second medium a a higher or lower index of refraction than where the ray was before/after the transmission? For the ray that experiences transmission, does it travel a distance of "t", "2t", or "t/2"? Light takes the same path towards the soap bubble (1, and 2.) but the light that leaves the soap bubble comes from two different paths (1, and 2) = 720nm d ------------- 1, 2 n = 1 n = 1 n = 1.2 Examine the path for Ray 1 Does the light experience reflection? If so, Is the reflective surface a higher or lower index of refraction than where the ray was before/after reflection? Does the light experience transmission? If so, is the second medium a a higher or lower index of refraction than where the ray was before/after the transmission? Examine the path for Ray 2 Does the light experience reflection? If so, Is the reflective surface a higher or lower index of refraction than where the ray was before/after reflection? Does the light experience transmission?
