Answer:
Hacksaw blade because it is metal.
Answer:
1.45
Explanation:
Refractive index of the liquid is given as;
Refractive index =
But,
speed =
Since a certain light of specific wavelength was used during the same time, let the time be represented by t.
So that;
speed of light in vacuum =
speed of light in the liquid =
Refractive index = ÷
= x
Refractive index =
= 1.4536
= 1.45
The refractive index of the liquid is 1.45.
