Resistance
The resistance of a conductor may be defined in terms of current passing through it and the potential difference across its ends. Resistance of a wire is the ratio of the potential difference 'V' across its ends and the current 'I' flowing through it. The unit of resistance is called the ohm, named..

. Join the pins R and S and produce the line on both sides. The ray O 1 E is the emergent ray. Join OO 1 . It is the refracted ray. With O as centre, draw a circle of a convenient radius 'r' in such a way that it cuts the incident and the refracted rays at F and G respectively. From F and G draw pe..

Consider the positions where Then y = 0 R = 0 Since the resultant amplitude is zero, these positions correspond to nodes. ..Laws of Refraction
Laws of Refraction - The incident ray, the refracted ray and the normal to the surface at the point of incidence all lie in one plane. For any two given pair of mediums, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant. The above law is called Sne..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
The tutor let me do the work and corrected me when i made a mistake. They didn't just show me how to do it. They gave me instructions. We managed to do several problems.I really like this service - cindy
i like this session,the tutor was really helpful and broke things down clearly were i could understand them better - Samantha
Looking for More Help!
