If the wavelength of a monochromatic source is 692 nm in vacuum,what is the wavelength from the same source when it passes through a liquid where the speed of light is 2.80 × 10⁸ m/s? (c = 3.00 × 10⁸ m/s) A) 1940 nm B) 741 nm C) 82 nm D) 646 nm E) 603 nm

The wavelength in the liquid is given by λ_liquid = λ_vacuum * (v_liquid / c_vacuum). Substituting the given values: λ_liquid = 692 nm * (2.80 × 10^8 m/s / 3.00 × 10^8 m/s) = 646 nm.
