Modeled after a sine wave, the length of a crinkle crankle wall is given by the integral + (), where () is the amplitude of the sine wave. For ( a = 1 ) {\displaystyle (a=1)} , this integral results in approximately 7.6404, indicating that the crinkle crankle wall is about 22% longer than a straight wall covering the same linear distance ...
A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...

[3] [4] Earliest known rear-view mirror mounted on a racing vehicle appeared on Ray Harroun's Marmon race car at the inaugural Indianapolis 500 race in 1911. [5]
A convex mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc. A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. [1] Convex mirrors reflect light outwards, therefore they are not used to focus light.
