1.) In special relativity, velocity is treated as:
Constant
Changing
Zero

2.) The rate at which light falls on a unit area is called:
Luminous Flux
Illuminance
Lux

3.) Snell’s Law relates refractive index to the angle of refraction and:
The angle of incidence
The frequency
The angle of reflection

4.) Lenses are able to work primarily due to the property of:
Reflection
Refraction
Interference

5.) The charge on one electron is also known as the:
Coulomb
Elementary charge
Standard

6.) The SI units of the electric field are the:
Coulomb
Maxwell
Newtons per coulomb
 
1) dunno (havent done relativity yet (= )
2) Illuminance. Lux is the unit. The flux is the rate of change if i'm not mistaken.
3) Angle of incidence.
4) Refraction
5) Elementary charge. Coulomb is a unit.
6) Newtons per Coulomb a.k.a Volts per meter.
