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>
The airtime is 9.8
the velocity is 0
It will be 133 on the moon
Answer:
λ = 5.734 x 10⁻⁷ m = 573.4 nm
Explanation:
The formula of the Young's Double Slit experiment is given as follows:

where,
λ = wavelength = ?
L = distance between screen and slits = 8.61 m
d = slit spacing = 1.09 mm = 0.00109 m
Δx = distance between consecutive bright fringes =
= 0.00453 m
Therefore,

<u>λ = 5.734 x 10⁻⁷ m = 573.4 nm</u>
Answer:
Farming
Explanation:
There were three droughts in the 1930s.
Farmers had deep plowed the land and killed the native grasses that trapped soil and moisture.
During the droughts, the moisture evaporated, and the loose soil turned to dust.
