I need some assistance with these assignment. reflection and refraction Thank you in advance for the help! Also, it has aided in the understanding on what makes the objects visible. The law of reflection The rule of reflection holds “for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected” (Anonymous, 2010). Reflection occurs when the wave travels through one medium to another. This is referred to as refractive index of the media. I order to determine the refractive index of different media, the following formula is used. n=c/v whereby, “n is the refractive index of the material, c represents speed of light in vacuum and v is the speed of light in vacuum” (Reeves, 2008). According to the law of reflection, the angle of incidence and the angle of reflection falls on the same reflecting surface and are equal and on opposite sides of the normal line (Kosso, 1998). Also, there is an assumption of a normal line which is an imaginary line perpendicular to the plane mirror surface and is the central line between incident and reflected lines (appendix 1). When reflection occurs on an even surface, it forms a mirror image which appears overturned from right to left. However, when specular reflection occurs at a curved surface, these forms magnified or de-magnified images. Causes of reflection The nature of reflection depends on the surface in which the waves come into contact with (Jacobs &amp. Schulman, 2008).
