Fading Signals: Inverse Square Law Explained

As a signal travels away from Earth, it spreads out and weakens with terrifying speed. Understanding the inverse square law explained is vital for anyone trying to talk to a probe at the edge of the solar system. If you...

Questions: 20 | Attempts: 10 | Last updated: Feb 27, 2026

Sample Question 1
Which of the following best defines the relationship described when the inverse square law explained the behavior of light or radio waves?

Intensity is directly proportional to distance

Intensity is inversely proportional to distance

Intensity is inversely proportional to the square of the distance

Intensity is constant regardless of distance

Intensity is directly proportional to the square of the distance

Sample Question 2
The total power emitted by a deep space probe decreases as the signal travels further away from the source.

True

False

Sample Question 3
If a spacecraft travels to a distance 4 times further from Earth than its original position, how is the inverse square law explained in terms of its new signal strength?

The signal is 1/4 as strong

The signal is 1/8 as strong

The signal is 1/16 as strong

The signal is 4 times stronger

The signal is 16 times stronger
