Concave Mirror
We know that a cut out of a reflective sphere is a spherical mirror. If the reflective surface is on the side curved inwards, it is a concave mirror. Concave mirrors are commonly used as shaving mirrors or by dentists and even in telescopes. The reflected image is magnified but the field of view is limited. Concave mirrors are also called converging mirrors.
Convex Mirror
Similarly, if the reflective surface is curved outwards, it is a convex mirror. Convex mirrors are used extensively as part of car mirrors. Depending on the focal length, the reflected image is reduced in size but the field of view is more. This is very useful for drivers as the blind spots are drastically reduced. Convex mirrors are also called fish eye or diverging mirrors. You can recognize these mirrors easily as the outward bulge is quite evident most of the time.

There are five basic laws of chemical combination that govern the chemical combinations of elements:
1. Law of Conservation of Mass
In simple terms, this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant. Antoine Lavoisier gave this law in the year 1789 based on the data he obtained after carefully studying numerous combustion reactions.
2. Law of Definite Proportions
Joseph Proust, a French chemist stated that the proportion of elements by weight in a given compound will always remain exactly the same. In simple terms, we can say that irrespective of its source, origin or its quantity, the per cent composition of elements by weight in a given compound will always remain the same.
3. Law of Multiple Proportions
This law states that if two elements combine to form more than one compound, the masses of these elements in the reaction are in the ratio of small whole numbers. This law was given by Dalton in the year 1803.
4. Gay Lussac’s Law of Gaseous Volumes
In 1808, Gay Lussac gave this law based on his observations. This law states that when gases are produced or combine in a chemical reaction, they do so in a simple ratio by volume given that all the gases are at the same temperature and pressure. This law can be considered as another form of the law of definite proportions. The only difference between these two laws of chemical combination is that Gay Lussac’s Law is stated with respect to volume while the law of definite proportions is stated with respect to mass.
5. Avogadro’s Law
Avogadro proposed this law in the year 1811. It stated that under the same conditions of temperature and pressure, an equal volume of all the gases contains an equal number of molecules. This implies that 2 litres of hydrogen will have the same number of molecules as 2 litres of oxygen given that both the gases are at the same temperature and pressure.

Binary Number System: According to digital electronics and mathematics, a binary number is defined as a number that is expressed in the binary system or base 2 numeral system. It describes numeric values by two separate symbols; 1 (one) and 0 (zero). The base-2 system is the positional notation with 2 as a radix.
The binary system is applied internally by almost all latest computers and computer-based devices because of its direct implementation in electronic circuits using logic gates. Every digit is referred to as a bit.
