Answer:
10432.19076 m
Explanation:
= Wavelength = 660 nm
d = Diameter of pupils = 6 mm
s = Distance between lights = 1.4 m
L = Distance from observer
From Rayleigh's criteria we have
As is small
So, the equation becomes
The car is 10432.19076 m from me

Answer:
Emission spectrum
Explanation:
The emmison spectrum is unique to every elements
Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light.
The color band indicate the amount of energy emitted in form of electromagnetic radiation.
When electrons in an atom gain energy, the become excited, on falling and losing their energy, they return to their ground state releasing the measure of energy they absorbed in transitioning.
The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.
