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 activation energy was used to start the chemical reaction in the burning marshmallow?
Sonja [21]

Answer:

This question is incomplete

Explanation:

This question is incomplete. However, let's understand some terms

Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.

The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
