Apparent depth is less than real depth due to the refraction of light as it passes from water to air. When light rays travel from a denser medium (like water) to a less dense medium (like air), they bend away from the normal, making objects submerged in water appear closer to the surface than they actually are. This bending of light causes our perception of depth to be distorted, leading to the phenomenon where objects look shallower than they truly are.
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.

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
The depth of a pond appears less than its actual depth due to light refraction. When light passes from water to air, it bends, causing objects submerged in the water to look shallower than they are. Additionally, the clarity of the water and the angle of observation can further distort our perception of depth. This optical illusion is common in various bodies of water.
Use a wattmeter, as it only reads 'real power' of your load. Use an ammeter and a voltmeter, and the product of the two readings will give you 'apparent power' of your load. Since apparent power is the vector sum of real power and reactive power, use the following equation to find the reactive power of your load: (reactive power)2 = (apparent power)2 - (real power)2
Apparent power is VA. Real power is W reactive power is VAR. Under an inductive+resistive load the VA is higher than W
Yes
When the depth of filling is less than the thickness (less than complete), it is specified inside the plug weld symbol!!!
NO for Integers NO for Real Numbers proof 1 * any integer is not bigger than that integer nor is 0 * any integer. proof for Real Numbers is easier any real < 1 * any real > 0 is not larger than the second Real for example .5 * 1 = .5 is less than 1 or .5 * 2 = 1 less than 2 or .5 * = 1 less than 2 or -1 *3 = -3 less than 3 so all fractions times a positive Real is less than that positive Real All negative numbers times a positive Real is less than that positive Real and 0 or 1 times all positive Reals is also less than that positive Real NO NO NO is the answer
Yes, apparent depth can pose risks while swimming. This optical illusion occurs when the water's surface refracts light, making objects appear shallower than they are. Swimmers may misjudge the depth, leading to potential injuries from diving into shallow water or colliding with submerged obstacles. It's crucial to assess water depth accurately to ensure safety while swimming.

Apparent weight of an object is the weight of an object when the object is partially or totally immersed in a fluid{liquid/gas} normally apparent weight of an object is less than the real weight of an object due to an upward force {upthrust} which is produced by the pressure difference inside the fluids.
