The speed of light in water is 2.25 x 108 m/s. What is true about the index of refraction of water?
djverab [1.8K]
Light speed in water is 2.25 times 10^5 m/s so the index of refraction is higher than the index of refraction of light in a vacuum which is 1.0. (speed in vacuum for light is 300,000 km/s)

Index of refraction of light in water is 3.0 time 10^5 m/s divided by 2.25 times 10^5 m/s = 1.33.

Hope this is what you wanted.

What is the water intake of gymnosperms​
ad-work [718]

Answer:

Check down

Explanation:

Gymnosperms, like angiosperms (the flowering plants), differ from seedless plants (like mosses and ferns) in not requiring water for sperm to swim in to reach the egg. This means that the movement of pollen (male gamete) to ovule (female gamete) in seed plants relies on airborne transport, not water transport.
