in this reaction meso form of tartaric acid is formed in which half of the molecule is the mirror image of other half so the optical activity is cancelled out....

Are diastereomers optically active?
Not necessarily , the meso form is optically inactive.
What is difference between a racemic mixture and a meso compound?
Both are optically inactive, but for different reasons. A racemic mixture contains chiral molecules that, individually, are optically active. But the mixture contains optically active enantiomers, which essentially cancel out each other's optical activity (one enantiomer rotates light one way, the other rotates it back). A meso compound, however, is optically inactive on its own. It can have chiral centers within its structure, but due to symmetry it will still be optically inactive.
Write the name of optically inactive amino acid?
Glycine, or aminoethanoic acid is the only amino acid that is not optically active as it does not contain a chiral carbon. C2H5NO2
What a zero specific rotation represent?
It means substance is optically inactive ,it is either a Recemic mixture or a Meso form of a compound
Why meso compounds are optically inactive?
A meso compoundis a molecule with multiple stereocenters that is superimposable on its mirror image. These particular traits lead to specific qualities that meso compoundsdo not share with most other stereoisomers. One such quality is the internal mirror plane. Optically inactive compounds are any that cannot be superimposed on itself.

An optically inactive amino acid is?
Glycine
What is asymmetrical symmetry?
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.

What is A mixture of equal amounts of two enantiomers?
its called a racemic mixture and is optically inactive

Glycine, or aminoethanoic acid is the only amino acid that is not optically active as it does not contain a chiral carbon. C2H5NO2
Racemic mixtures and meso compounds?
solution containing equal amounts of enantiomers.it is optically inactive.
How do you distiguish for the optically active and in active?
First of all we should know what optically active molecules are "Those molecules which possess asymmetric(chiral) carbon atoms have the ability to rotate the plane polarized light(light of one wavelength having its electrical character vibrating in one direction only) to the left or to the right are known as Optically active molecules" while those molecules not following the former scenario are known as Optically Inactive molecules. All in all molecules having asymmetric carbon atoms are known as optically active molecules for example glucose(rotate plane polarized light to the left) & fructose(rotate plane polarized light to the right) are optically active molecules. While molecules lacking asymmetric carbon atoms are optically inactive molecules for example water is optically inactive. And that's how we can distinguish between these two molecular classifications.

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.
Why silicon germanium semiconductors are not used to produce lasers?
Basically Si and Ge are optically inactive materials because of it's indiect band gap.That's why people are not using this for producing lasers. Generally we are using Optically active materials are used for Laser Production. Ex:Ga-As
