Answer:
Distance per unit time
Explanation:
Speed is the rate at which someone or something is able to move or operate.
Conservation means to improve something to prevent loss or decay
That's why energy can't be created or destroyed
Answer:
Ratio of wavelength will be 1.1982
Explanation:
We know that velocity in any medium is given by , here c is the velocity of light and n is the refractive index
We know that wavelength is given by , from the relation we can see that wavelength is inversely proportional to the refractive index
We have given refractive index of carbon disulfide = 1.632
And refractive index of ethyl alcohol = 1.362
So ratio of wavelength of ethyl alcohol and carbon disulfide =
