Question

parallel rays from a distant object are traveling in air and then are incident on the concave end of a glass rod with a radius of curvature of 15.0 cm. the refractive index of the glass is 1.50.

Answer 1

Parallel rays from a distant object incident on the concave end of a glass rod with a radius of curvature of 15.0 cm will refract and converge to form an image inside the glass rod. The exact location of the image can be determined using the lens equation, and the magnification can be calculated using the magnification formula.

Step-by-step explanation:

When parallel rays from a distant object travel through air and then are incident on the concave end of a glass rod with a radius of curvature of 15.0 cm and a refractive index of 1.50, the rays will refract and converge to form an image inside the glass rod. The exact location of the image can be determined using the lens equation, which relates the object distance (distance of the object from the lens), the image distance (distance of the image from the lens), and the focal length of the lens.

The magnification of the image can be calculated using the magnification formula, which compares the height of the image to the height of the object. In this case, since the rays are parallel, the height of the image can be expressed as a ratio of the image distance and the object distance.
