\f3- Move the protractorto a place where its center aligns well with the intersection point behueen the vertical dotted ine and the horizontal interface between two materials. Click red button on laser and observe how light travels. )- Move the laser so that the incident angle 50". Use the protractorto measure the refracted angle and reected angle Md? respect to the name! when the light encounters the boundary as listed in the table: at to water, air to glass, and air to a material with the retractive index 1.600. For each case, use the speedometer to measure and record the speed at light traveing in the bottom medium. 3- Czlculate n1 sin B. and n2 sin 0; and compare these two values by nding the '36 ditferenoe between them. Are they close to each other as Snell's Law predicated? '34: difference = ditferenoe between these two vaIJes thigger of these two values x 100% Incident Reected Reflected Speed it n' sin 0' n; sin 02 \"ll: ame-e angle 0' angle angle B; the bottom between n' sin B1 material and n2 sin 32 Top: air n1=1.000 Bottom: water n:='1.333 Top: air 50' I11=1 Bottom: glass nz=1.500 Top: air 60" n1=1.000 Bottom: n2=1.600 )- Based on your data, answer the folowing questions: Is the reected angle the same as the incident angle for each case? Is the refracted angle smaller or biggerthan the incident angle tor each case? As the refractive index in the bottom material increasesI does the light bend Edmonton fun the incident ray? As the refractive index in the bottom material increasesI does the speed ct light slow down more or less? Is this what you expected?
