Lucite has a refractive index of n=1.50. This means that the speed of the light in lucite is decreased according to:

where

is the speed of light in air. Putting the number in the formula, we find that the speed of light in lucite is

The frequency of the light is

, so now we can calculate the wavelength in lucite by using the formula:

<span>Therefore, the correct answer is (2) 393 nm.</span>
Answer:
appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity
Explanation:
Gravity is the name of the force that keeps the planets in orbit
The concept of work-energy theorem has become much of a fundamental principle in the field of physics, mechanics, and engineering. In addition, this theory primarily states that the change of kinetic energy of the system is equal to the sum of the work done that is acted by all forces on the object.
