For better reflection
The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.
To achieve total internal reflection in a prism, the index of refraction (n) must be greater than the sine of the critical angle. For a critical angle of 45 degrees, the minimum index of refraction can be calculated using ( n = \frac{1}{\sin(45^\circ)} ), which gives ( n = \sqrt{2} ) or approximately 1.414. Therefore, the minimum index of refraction for a glass or plastic prism used in binoculars must be at least 1.414.
The opposite of binoculars would be a monocular, which is a single lens optical instrument used for viewing distant objects with one eye.
Prisms are used in binoculars to bend and reflect light, allowing the viewer to see a magnified image. Binoculars typically use either Porro prisms or roof prisms to achieve this.
No, the official spelling doesn't have a prefix.

A triangular prism reflects light at specific angles. Many are used in equipment such as binoculars and telescopes to reduce their physical size.

No ! The images formed by a mirror are not perfect !!The finest images are those formed by a right angled PRISM . However the rays from the object need to fall perpendicularly on prism's surface . Thus for convenience mirrors are used .

Mixter right-angled forceps are commonly used in surgical procedures for grasping and manipulating delicate tissues or structures in confined spaces, such as during neurosurgery or vascular surgery. The right-angled design allows for better access and visibility in hard-to-reach areas without causing damage to surrounding tissues.

Set square
No. It can be used on any triangle.

The minimum index of refraction for total internal reflection at a 45-degree angle is 1.41. This means that the glass or plastic prism would need to have an index of refraction greater than or equal to 1.41 to achieve total internal reflection at that angle.
Sine is a mathematical formula used in right angled triangles. It is Opposite/Hypotenuse . Opposite being the angle opposite the angle of your choice and Hypotenuse being the longest side in your right angled triangle.
