Answer:
b) 2.3 m
Explanation:
Apparent depth is an optical illusion that occurs due to the bending of light rays as they pass from one medium to another medium with different refractive indices.
Apparent depth:
[tex]\boxed{\bf D = d* \dfrac{n_2}{n_1}}\\\\D \ is \ the \ \bf \ apparent \ depth\\[/tex]
d is the depth of water. Here, d = 3 m
[tex]\sf n_2 \ \text{ is the \bf refractive index of air} \ ; n_2 = 1 \\\\n_1 \ \text{is the \bf refractive index of water } \ ; \ n_1 = 1.33[/tex]
[tex]\sf D = 3 * \dfrac{1}{1.33}\\[/tex]
D = 2.25
D = 2.3 m
