Answer:
Refraction
Explanation:
Refraction is a phenomenon typical of light waves. It occurs when a ray of light passes through the interface between two mediums: when doing so, the ray of light changes speed and also changes direction, according to Snell's Law:
where
are the index of refraction of the first and second medium, respectively
are the angle of incidence and refraction, respectively
When white light enters a prism, therefore, it undergoes refraction, and it changes direction.
However, the index of refraction of a material, n, depends also on the wavelength of the light. In particular, the shorter the wavelength, the higher the index of refraction.
This means that as white light enters a prism, the different wavelengths contained in the white light are refracted at different angles: as a result, the 7 colors of light will separate, and that is why we observe the rainbow when white light enters a prism.
They need to be pressurized because the pressure in the space shuttle is different in space so they need to have air to breathe for when the pressure changes.
Answer:
7.07 hours
Explanation:
divide the distance by the speed
so in this case, divide 672 by 95
Answer:
i would look this up cuz i had this in a quiz once and found it on something called quizlet
