Calculating Light Travel Time for 60 cm

AI Thread Summary
To calculate the time it takes for light to travel 60 cm at a speed of 2.10^8 m/s, the formula distance/speed = time taken is applied. The correct speed of light in the medium is confirmed to be 2.10^8 m/s, not 2.10^-8 m/s. For a distance of 60 cm (0.6 m), the time taken can be derived by dividing the distance by the speed. This results in a calculated time of 0.000003 seconds, or 3 microseconds. Accurate unit conversion is emphasized for correct calculations.

i tried to do something but not enough.. :(

What's the definition of speed? (Rewrite the speed of the light more carefully. I doubt you meant 10^-8.)
 


yes,it can be 2.10^8 m/s
 


if the velocity of light in the medium is assumed to be 2.10^8 m/s, right?

so, if it had asked:

how much time does it take the light to travel through the distance of 2.10^8 m?

You would have answered 1 second.

From here, you can derive the formula.

distance/speed = time taken

Just be sure to convert the units as needed :)
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
