Explanation:

According to the general theory of relativity, spacetime curves due to the energy it contains. Since mass is a form of energy, "create" gravity. That is, gravity is the effect observed as a consequence of the curvature of spacetime. Therefore, gravity curves the path of light because it curves the space through which light passes.

A source emits monochromatic light of wavelength 495 nm in air. when the light passes through a liquid, its wavelength reduces t

Katyanochek1 [597]

By definition, the refractive index is
n = c/v
where c = 3 x 10⁸ m/s, the speed of light in vacuum
v = the speed of light in the medium (the liquid).

The frequency of the light source is
f = (3 x 10⁸ m/s)/(495 x 10⁻⁹ m) = 6.0606 x 10¹⁴ Hz

Because the wavelength in the liquid is 434 nm = 434 x 10⁻⁹ m,
v = (6.0606 x 10¹⁴ 1/s)*(434 x 10⁻⁹ m) = 2.6303 x 10⁸ m/s

The refractive index is (3 x 10⁸)/(2.6303 x 10⁸) = 1.1406

Answer:

B = 2.5 10⁸ Pa

Explanation:

The volume modulus is defined by

B = $- \frac{P}{ \frac{\Delta V}{V} }$
