Final answer:
The point where the reflected rays meet in a concave mirror can be determined using the mirror equation. In this case, with a focal length of 10 cm, the reflected rays meet at a distance of 10 cm from the mirror.
Step-by-step explanation:
The point where the reflected rays meet can be determined using the mirror equation. The mirror equation is given by: 1/f = 1/v - 1/u, where f is the focal length of the mirror, v is the image distance, and u is the object distance.
In this case, the parallel beam of light is incident on a concave mirror. Since the focal length of the mirror is 10 cm, we have f = 10 cm. Since the beam of light is parallel, the object distance (u) would be infinity.
Substituting the values into the mirror equation, we have: 1/10 = 1/v - 1/infinity. Since the reciprocal of infinity is 0, the equation simplifies to: 1/10 = 1/v.
Solving for v, we find that the image distance is 10 cm. Therefore, the point where the reflected rays meet is located at a distance of 10 cm from the concave mirror.
