The left atrium collects oxygen-rich blood from the lungs, and upon contraction, transfers it to the left ventricle. The left ventricle then pumps the oxygenated blood to the rest of the body.
Considering only two rays is more convenient for the clarity of the ray diagram. While an infinite number of rays could originate from each small portion of the extended object, choosing two specific rays simplifies the construction of the diagram. ...
The relationship R = 2f means that the principal focus of a spherical mirror is located midway between the pole and the center of curvature. This geometric relationship simplifies the understanding of the mirror’s optical properties, particularly for mirrors with ...
Spherical mirrors with small apertures, the radius of curvature (R) is found to be equal to twice the focal length (f). Mathematically, this relationship is expressed as R = 2f. This implies that the principal focus of a spherical mirror ...
