Earth is a spherical concave
WebDec 21, 2024 · 90 Years of Our Changing Views of Earth Indirect evidence of the Earth’s spherical shape has existed for a long time, but the photographic proof was lacking until well into the 20 th century. WebNonetheless as far as optical instruments go, most spherical mirrors are spherical caps. Start by tracing a line from the center of curvature of the sphere through the geometric center of the spherical cap. Extend it to infinity in both directions. This imaginary line is called the principal axis or optical axis of the mirror.
