Answer:
Visible light from the Sun
Explanation:
The visible light is known to be a portion of the electromagnetic spectrum that can be seen with naked eyes. It is a form of electromagnetic radiation.
Other forms of the electromagnetic radiation are the infrared and ultraviolet.
The visible light is found or falls within the range of electromagnetic radiation spectrum between the infrared and ultraviolet.
Among the electromagnetic radiation, the visible light is the portion that supplies the energy which warms the earth's surface.
The population decays by a factor of (1/2 )^1/4 every hour.
<h3>
Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Let y represent the bacteria population after x hours.
A bacteria population decreases by a factor of 1/2 every 4 hours.

The population decays by a factor of (1/2 )^1/4 every hour.
