of external strain has been taken into consideration to propose the approach. From our proposed model it is found that graphene under relaxed or symmetrical strain distribution is a zero bandgap semiconductor. However a band gap is opened as the asymmetrical strain is applied to it. It is seen that upto a certain level of strain (i.e. 12.2 % parallel to carbon-carbon bond and 7.3% perpendicular to carbon-carbon bond) the band gap of graphene increases and then begin to fall . So‚ four different assumptions

1.0003‚ and water has a refractive index of about 1.3330. If a person looks at a straight object‚ such as a pencil or straw‚ which is placed at a slant‚ partially in the water‚ the object appears to bend at the water’s surface. This is due to the bending of light rays as they move from the water to the air. Once the rays reach the eye‚ the eye traces them back as straight lines (lines of sight). The lines of sight (shown as dashed lines) intersect at a higher position than where the actual rays originated
