Hi
It is difficult to say whether neet 2012 will be postponed or not depends upon the condition of pandemic.
If the surge in covid - 19 cases continues then chances are high that it will be postponed but if the situation becomes under control then it will not be
Hey there,

When light travels from denser to rarer medium angle r (angle of refraction) is always greater than angle I (angle of incidence). For a particular angle of incidence ,angle r in right angle is 90degree. The angle cc is called critical angle.
Hi there,
At any given instant all the points of wavefront act as a secondary source of light. The waves generated by these secondary sources have light of wavelengths frequency and velocity. They make their own wavelets. Finally the common tangent envelopes overall wavelets gives secondary wavefront.
Hope it helps!
Semiconductors are those materials which have conductivity between conductor (copper,silver) and insulator( glass, diamond).
It can control bthe number the charge carriers ( electrons+holes).
It can control conductivity.
It gives unidirectional current which current will flow in one direction.
Primary key is the set of attributes that uniquely identifies the records of the table. If we apply primary key in a column then we cannot add duplicate value to it.
Foreign key is a non key attributes those whose values are derived from primary key of some
To read data from CSV We should use reader function to generate reader object. The reader function is developed to take each row of a file and make a list of all columns. Now we have to choose the column we want the variable data for .

In this experiment more intensity is more energy,but in thia experiment different intensities give electrons of same energy.
If wavefront carry energy then large number of electrons should be emitted but it is not happening here.
If frequency of light is less than threshold frequency then no electron
The process of superimposing the information content of a low frequency baseband, modulating signal on a high frequency carrier signal by altering it's characteristics ( amplitude,phase and frequency) is called modulation. Following bare the needs of modulation:
1) reduces the height of antenna
2) increases the range of
Hello,
Yes, a candidate can choose 4 exam centers for NEET UG. Any city can be chosen from the designated exam centers across India but you should choose the exam centers by taking in to consideration the transportation facility, ease to travel, distance, accomodation and convenience. You can choose exam
