What is the apparent depth of an object whose real depth below the water surface is 5 m?

The apparent depth of an object submerged in water can be calculated using the formula: apparent depth = real depth / refractive index. Since the refractive index of water is approximately 1.33, the apparent depth of an object 5 meters below the water surface would be around 3.76 meters.


What are the differences between real depth and apparent depth?

Real depth is the actual distance between two points in a medium, while apparent depth is the distance between those points as perceived by an observer due to the bending of light. Apparent depth is affected by the refractive index of the medium, causing objects to appear closer or further away than they actually are.


Is centrifugal a force?

The centrifugal force is an apparent (ficticious) force, caused by a rotational movement. The amount of the apparent centrifugal force can be calculated by the same formula as the amount of the real centripetal force.


What is meaning of real and apparent?

Real means existing in fact Apparent means obvious


What is the real gas formula used to calculate the behavior of gases under non-ideal conditions?

The real gas formula used to calculate the behavior of gases under non-ideal conditions is the Van der Waals equation.


How do you calculate kilovoltamps when kilowatts is known?

To calculate kilovolt-amps (kVA) when kilowatts (kW) is known, you can use the formula: kVA = kW / power factor. The power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical circuit.


How do you calculate the phase constant in a given system?

To calculate the phase constant in a given system, you can use the formula: phase constant arctan(imaginary part / real part). This involves finding the ratio of the imaginary part to the real part and then taking the arctangent of that ratio.


How to calculate a profitable real eatate investment?

A profitable in real estate investment can be calculated using the following formula: Return on investment (ROI)=(gain from investment-cost of investment)/cost of investment.


How to calculate the GDP deflator?

To calculate the GDP deflator, divide the nominal GDP by the real GDP and multiply by 100. The formula is: GDP Deflator (Nominal GDP / Real GDP) x 100. This measure helps adjust for inflation and shows how much prices have changed over time.


Why the position of fish inside the water seem to be at less depth than that of its actual position?

Light coming from the fish under water deviate from its original path due to refraction phenomenon and its image is displaced from its actual position. The image of fish is appeared at shallower depth than its actual depth


True power divided by apparent power?

Real Power: The actual power in Watts or K-Watts in AC or DC Circuits Apparent power: The Power in Inductive or Capacitive Circuits have Phase Lag & Lead measured in Volt Amperes VA or Kilo Volt Amperes KVA


Why VAR meter does not measure real and apparent power?

A VAr meter only measures the reactive (imaginary) power. Apparent power is a combination of real and reactive power; thus having a VAr meter will not suffice to measure apparent power. Likewise, because the VAr meter only measures reactive power, it does not provide any information on real power.
