The power reflected by a wave with incident power of 16 units is(Given...
Answer: d
Explanation: The fraction of the reflected to the incident power is given by the reflection coefficient. Thus Pref = R2xPinc. On substituting the given data, we get Pref = 0.52 x 16 = 4 units.

To calculate the power reflected by a wave, we need to use the reflection coefficient. The reflection coefficient is a measure of how much of the incident power is reflected back from the boundary.
Given that the reflection coefficient is 0.5, we can calculate the power reflected as follows:
1. Calculate the reflected power:
- The reflection coefficient is given by the equation:
Reflection coefficient = (Power reflected / Power incident)
- Rearranging the equation, we can find the power reflected:
Power reflected = Reflection coefficient * Power incident
2. Substitute the given values into the equation:
- Reflection coefficient = 0.5
- Power incident = 16 units
Power reflected = 0.5 * 16 = 8 units
Therefore, the power reflected by the wave is 8 units.
Explanation:
The reflection coefficient represents the ratio of the reflected power to the incident power. In this case, the reflection coefficient is given as 0.5, which means that 50% of the incident power is reflected back.
To calculate the power reflected, we multiply the reflection coefficient by the incident power. Since the incident power is given as 16 units, we can calculate the power reflected as 0.5 * 16 = 8 units.
So, the correct answer is option D, which states that the power reflected by the wave is 8 units.
