A fish in water sees an object which is `24cm` above the surface of water. The height of the object above the surface of water that will appear to the flash is `(mu=4//3)`

Text Solution

AI Generated Solution

To solve the problem of how high an object appears to a fish in water, we can use the formula that relates the apparent depth (or distance) and the real depth (or distance) through the refractive index (μ) of the medium. ### Step-by-Step Solution: 1. **Understand the Given Information:** - The height of the object above the water surface (real distance) = 24 cm. - The refractive index of water (μ) = 4/3. ...

An under water swimmer is at a depth of 12 m below the surface of water. A bird is at a height of 18 m from the surface of water, directly above his eyes. For the swimmer the bird appears to be at a distance from the surface of water equal to (Refractive Index of water is 4/3)

A point source is placed at a depth h below the surface of water (refractive index = mu ). The medium above the surface area of water is air from water.

A beaker is filled with water as shown in figure (a). The bottom surface of the beaker is a concave mirror of large radius of curvature and small aperture. The height of water is h = 40 cm . It is found that when an object is placed 4 cm above the water surface, the image coincides with the object. Now the water level h is reduced to zero but there will still be some water left in the concave part of the mirror as shown in figure (b). The new height of the object h' above the new water surface so that the image again coincides with the object, will be (Refractive index of water = 4//3 )
