Answer:
B. it showed that the wave nature of light is a probability statement of where photons are going to be
Explanation:
When the light propagates through a medium it is taken to act as a wave, it shows all the features of a wave such as reflection, refraction, diffraction.
- But when the light ray is incident on a surface generating an energy interaction with the particles of the matter on which it is incident then it is treated as matter. Light is made of particles called photons.
- The collision of photons with the surface electrons in some materials leads to the ejection of the valance electrons from the surface in excited state.
Energy of photon is given as:
where:
h = Planck's constant
frequency of the wave
To determine the number of significant figures in a number use the following 3 rules: Non-zero digits are always significant. Any zeros between two significant digits are significant. A final zero or trailing zeros in the decimal portion ONLY are significant.
Speed = (distance covered) / (time to cover the distance).
= (1.92 meters) / (4.47 x 10⁻⁸ second)
= 42,950,000 meters/second (rounded to the nearest 10,000 m/s)
That's about 96.1 million miles per hour, or about 14% of the speed of light.
