Answer:
It is example of Closed system
Who was the first president?
It could be changed by asking
“Who was the first president and what was there scientific accomplishment?”
These are the reactants because they are on the left side of the equation.
Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
<span>2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ </span>
<span>(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ </span>
<span>4.007*10⁻⁷ m = λ </span>
<span>The wavelength of the yellow light = 4.007*10⁻⁷ m<span> </span></span>

A) the space inbetween the waves
B) frequency
C) the frequency gets higher
