A change in velocity, A change in direction, or a change in both velocity and direction.
It would be{ 4) 2 silver spoons}<span>
that the material reflects light but does not refract it</span>
R=U/I so R= 7V/0.5A = 14 Ω
Now we just substract botg resistors from the total to get R3: 14 - 4 - 1= 9Ω
How does the angle of incoming light compare to the angle of light reflecting off of the surface?
- <em>The measurements of the angles are equal.</em>
