What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45 degrees?
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.
What is the minimum index of refraction for a glass or plastic prism to be used in binoculars so that total internal reflection occurs at 45.0 and 8728?
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.
What is the opposite of binoculars?
The opposite of binoculars would be a monocular, which is a single lens optical instrument used for viewing distant objects with one eye.
What is used to bend light in binoculars?
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.
Does the word binoculars has a prefix?
No, the official spelling doesn't have a prefix.
How is a prism used in your every day life?
Binoculars, cameras, telescopes,
What are the uses of a triangular prism?
A triangular prism reflects light at specific angles. Many are used in equipment such as binoculars and telescopes to reduce their physical size.

Why are mirror images perfect?
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 .
What tool is used to draw right angled triangles?
A protractor
What is the use of mixter right angled forceps?
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.
Who used the Pythagoras theorem?

What is the name for the Right angled instrument used for technical drawing?
Set square
Can trigonometry be applied only in right angled triangles?
No. It can be used on any triangle.
What mathematician is credited with a theorem specifically used in right angled triangles?
Pythagreos

What is does sine mean?
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.
