A boat has green light of wavelength λ = 500 nm on the MAST. What wavelength would be measured and what colour would be observed for this light as seen by a diver submerged in water by the side of the boat? Given n W= 4/3

Question

A boat has green light of wavelength λ = 500 nm on the MAST. What wavelength would be measured and what colour would be observed for this light as seen by a diver submerged in water by the side of the boat? Given n W= 4/3 (A) Green of wavelength 500 nm (B) Blue of wavelength 376 nm (C) Green of wavelength 375 nm (D) Red of wavelength 665 nm

When light travels from rarer to denser medium its wavelength reduces. Wavelength in water =(λa/μw) =(500/(4 / 3))=375 nm ≈ 376 nm text (Blue colour)

Q. A boat has green light of wavelength $λ$ = $500 nm$ on the $M A ST$ . What wavelength would be measured and what colour would be observed for this light as seen by a diver submerged in water by the side of the boat?
Given $n_{W} = 4/3$

Green of wavelength $500 nm$

Blue of wavelength $376 nm$

Green of wavelength $375 nm$

Red of wavelength $665 nm$

When light travels from rarer to denser medium its wavelength reduces. Wavelength in
water $= \frac{λ _{a}}{μ _{w}}$
$= \frac{500}{( 4/3 )} = 375 nm \approx 376 nm (Blue colour)$
