NettetConsider the below diagram to answer the questions: Angle of incidence = i = 90°-56°=34°. From the law of reflection, angle of reflection = r = i = 34°. Angle made by the reflected ray and the surface = q = 90°-r = 90°-34°=56°. Angle made by the incident and reflected rays = i+r=34°+34°=68°. 2,63,148.

NettetThere are several definitions of the normal line of a flat mirror. Normal line is the line perpendicular (at 90°) to the mirror. or The normal line is an imaginary line at 90° to … Nettet4. sep. 2024 · You must observe the cleavage angles to tell them apart. Cleavage angles in pyroxene are near 90°, so expect it to look boxy and form right angles. Cleavage angles in amphibole are 60° and 120°, so expect a more bladed or pyramid-like appearance (Figure 7.11). Amphibole – cleavage angles at 60° and 120°. haralddestiny outlook.com
