What is bak-4 prism?
BAK-4 prisms are the best; they are made of superior optical glass that produces clearer images. BAK-4 prisms show a truer round, which translates to better light transmission and edge-to-edge sharpness. These are what you want in your binoculars.
How many images are formed if two parallel mirrors are put facing each other?
Very many. The glass of real mirrors is not perfectly clear and the reflective coating of real mirrors is not perfectly reflective so the images dim. But is not hard to get 50 or more spots of light when shining a laser pointer into such a mirror configuration. ------------------------------------------------------------ Edit:Actually, when you look at one of these mirrors, the number of images will increase continuously at the velocity "c", so you can accept that its limit is infinite, but in other hand it's finite because the speed of light "c" is finite, it's a physical "optical" paradox.
What happens when light is reflected?
Reflections occur when light bounces of a smooth and shiny surface. Glass mirrors have a thin layer of silver on the back so that light is reflected.
What are two examples of a parallel beam of light?

How will you compare prism to raindrops?
Light is refracted and reflected by a (glass) prism Light is refracted and reflected by a raindrop
What is the working principle of polarimeter?

What are stereo isomers?
plane polarised light is being used. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form. A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form. If the solutions are equally concentrated the amount of rotation caused by the two isomers is exactly the same - but in opposite directions. When optically active substances are made in the lab, they often occur as a 50/50 mixture of the two enantiomers. This is known as a racemic mixture or racemate. It has no effect on plane polarised light.
What is the difference between optical isomer and optically active isomer?
Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.
What is the difference between L amino acid and D amino acid?
L and D amino acids are both optical isomers of each other and only differ in their ability to rotate plane polarized light in opposite directions.
What is the difference between d ascorbic and L ascorbic acid?
l ascorbic acid and d ascorbic acid are optical isomers of each other. Optical isomers have the same physical and chemical properties but bend the plane of polarisation of polarized light in different directions.It is also called ChiralitySee the related link for more info on optical isomers.
How does the presence of a chiral carbon atom in a molecule give rise to the existence of a pair of stereoisomers?
Chirality does not give rise to a a pair of stereo-isomers but to a pair of optical isomers.Optical isomers are identical in every way but one: that the two isomers are mirror images of each other...they are not superimposeable...they are defined as + and - or laevo and dextro rotatory (left handed and right handed) because of the effect they have on polarised light. Polarised light is oriented in one plane and passing such light through a laevo rotatory optical isomeric substance it will be rotated through an angle and emerge in a different plane.In living organisms a higher proportion of one optical isomer over the other occurs.Substances produced in the lab have more or less equal proportions of each isomer and are called racemic mixturesA chiral carbon atom is defined as having four differentconstituent atoms or groups of atoms attached to it by means of single covalent chemical bonds.This confers a status of assymetry to this carbon atom.
What is the cause of optical activity?
Optical activity happens in a solution with components of quartz, sugar or certain gases. It is when the plane of linearly polarized light is turns to the direction of movement through the components.
What do you get when you react Propanal and hydrogen cyanide. Also why is it optically inactive and what name is given to such an inactive product?
I can't remember what you get but it's optically inactive because it's a racemic mixture. Which means that there is a 50:50 ratio of the (+) optical isomer and the (-) optical isomer. It's inactive because the (+) rotates plain polarised light clockwise and the (-) isomer rotates plain polarised light anticlockwise. So they cancel each other out because it's a racemic mix and therefore shows no optical activity.
What are optical substances?
Optically active substances are those substances that rotate the plane of polarized light to the left or right.
What is the light that passes through a polarizing filter?
Polarised light!
Dextro and levo rotatry compound?
dextro rotetary means rotate the plane polirised towards right hand side while Levo rotatry means the substance has tendency to rotate plan polarised light towards left hand side.
