Please help. A ray of light coming from the point (-1, 3, 2) is travelling in the directionof the vector 4i + j -2k and meets the plane x + 3y + 2z - 24= 0. Find the angle that the ray of light makes with the plane.
Tks!
Hello, pantera!
The angle between two vectors is given by: .A ray of light coming from the point (-1, 3, 2) is travelling in direction
and meets the plane
Find the angle that the ray of light makes with the plane.
The ray has direction: .
The plane has normal direction
The angle between the ray and the normal is:
. .
Hemce,
Therefore, the angle between the ray and the plane is about: .
