Under which condition does a light ray striking a concave mirror reflect off parallel to the principal axis?. . . A. when the in
cident ray passes from a point anywhere between the center of curvature and the focal point . . B. when the incident ray passes through the center of curvature . . C. when the incident ray passes through the focal point . . D. when the incident ray passes through a point beyond the center of curvature . . E. when the incident ray passes through a point anywhere between the focal point and the vertex . . can someone please explain thanks in advance
When the incident ray passes through the focal point, a light ray striking a concave concave mirror reflect off parallel to the principal axis. The correct option among all the options given in the question is the third option or option "C". I hope the answer comes to your help.
Multiply 8 by both numbers in the parentheses. -8x7 - 8x(-3.2) You should end up with -56 + 25.6 Next you add those two numbers and you end up with 30.4.
