Question

Energy flux may affect which of the following?

• A. \( \text{Lens} \)
• B. \( \text{Strength of the signal} \)
• C. \( \text{Aperture} \)
• D. \( \text{Declination} \)

Hint:

Think of energy flux as the 'brightness' of the light coming from the object – more brightness means a stronger signal.

Answer 1

The Correct Option is B

Energy flux, which is the rate of energy transfer per unit area, directly influences the strength of the signal received by a remote sensor. A higher energy flux from a target generally results in a stronger signal detected by the sensor. The lens and aperture of the sensor are components that control the amount of energy reaching the detector, but the energy flux from the target itself is what determines the initial signal strength. Declination is an astronomical term related to celestial coordinates.
