define ohms law and define refraction of light and reflection of light
Answers
Ohms law
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit.
Formula :-
V = IR
V is voltage
I is current
R is resistance
Reflection of light
Reflection of light is when the light bounces off a medium. If the medium has a smooth surface, then the angle of incidence is equal to the angle of reflection.
Refraction of light
Refraction of light is the change in the direction of light as it passes from one medium to another
Answer:
ohm's law states that the current I through the conductor is directly proportional to the potential difference V applied accross its two ends provided the physical states of conductor are unchanged.
if the ray of light comes to the interface of two mediums with different refractive index it changes suitably. this phenomenon is called as refraction of light.
when a light ray approaches a smooth surface it bounces back. this is called reflection of light.
