The speed remains constant.
The speed becomes zero.
The speed decreases.
What type of image is formed by a plane mirror?

Virtual and inverted.
Real and inverted.

What is the SI base unit used to measure the intensity of light?
Candela (cd)
Watt/meter squared (W/m^2)
Question #3: What limitation does Snell's Law face when applied to scenarios involving extremely intense laser beams passing from air into glass?
Nonlinear optical effects can occur at high intensities, modifying the refractive index and deviating from Snell's Law predictions.
Intense laser beams are too narrow for Snell's Law to apply due to insufficient interaction with the glass surface area.
At extreme intensities, laser beams exclusively reflect off surfaces making Snell’s law redundant for describing their path inside glass.
Laser beam intensity has no effect on its refraction according to Snell's Law, so there are no limitations present.
