The chemical formula for water, H2o means that each water molecule contains one oxygen atom and two hydrogen atoms. This is the formula for water which has a liquid form, a solid form as ice, and also a gaseous form as water vapor.
The Jovian planets contain large percentage of Gases its because they are formed outside of what they called as frost line where temperature is low enough for ice condensation unlike terrestrial planets formed close to the sun where the temperature is very appropriate for metal and rock to condense.
B.The wave will bend or defract
diffraction is the phenomenon of bending of waves around the edge of the obstruction in its path of motion. this happens more strongly when the dimensions of the slit is comparable with the wavelength of the wavelength undergoing the diffraction process. hence the correct choice would be B
The answer is 'A', they travel parallel to the direction of motion
Explanation:
It is given that,
Wavelength of red light, 
Power of the laser, 
(a) The energy carried by each photon is given by :
(b) Let n is the number of photons emitted by the laser per second. It can be calculated as :
Hence, this is the required solution.
