The Planck–Einstein relation

gives that E, the photon energy, is equal to h, Planck's constant, times <span>ν</span>, the frequency.
We can solve the equation in terms of frequency to get

We substitute our given energy,

, and Planck's constant,

.
Answer:
This line is a horizontal line, so it has an equation y=n, where n is a number.
In this case, because the y intercept is (0,2) the equation is y=2.
Let me know if this helps!
Answer:
149 people/ sq. miles
Step-by-step explanation:
Anchorage is a city in country Alaska.
Based on 2010 data, Anchorage has a population of 291826 people and the area coverage of the city is 1961.1 square miles.
We are asked to determine the population density of Anchorage city.
Therefore, the number of people living per unit square miles of Anchorage is given by
≈149 people/ sq. miles. (Answer)
