By definition, the refractive index is
n = c/v
where c = 3 x 10⁸ m/s, the speed of light in vacuum
v = the speed of light in the medium (the liquid).
The frequency of the light source is
f = (3 x 10⁸ m/s)/(495 x 10⁻⁹ m) = 6.0606 x 10¹⁴ Hz
Because the wavelength in the liquid is 434 nm = 434 x 10⁻⁹ m,
v = (6.0606 x 10¹⁴ 1/s)*(434 x 10⁻⁹ m) = 2.6303 x 10⁸ m/s
The refractive index is (3 x 10⁸)/(2.6303 x 10⁸) = 1.1406
Answer: a. 1.14
Answer:
the answers are 1 2 and 5!
Answer: The Earth's layer, which has the covering and layer, is made of a progression of things, or structural plates, that creep after some time. Along these lines, at intersecting limits, mainland outside is made and maritime covering is devastated. 2 plates slippy past each other structures a redesign plate limit.
The cat fell 1.0 m from the ground.
Using the formula
Here, 
Solving for t, the time it spent in the air is
The cat does not accelerate along the horizontal, so it has constant horizontal velocity. Since it strikes the floor 2.2 m from the table, then
Frequency of any wave = (the wave's speed) divided by (its wavelength)
Speed of light = about (3 x 10 to the 8) meters per second, in vacuum.
Frequency = (3 x 10 to the 8) / (4.1 x 10 to the -12) = 7.317 x 10 to the 19 Hz.
That's the same as 73,170,000,000 GHz.
Note:
That's the answer for the information given in the question, but the information in
the question is incorrect by 5 orders of magnitude. The wavelength of violet light,
or anything in the visible range, is a few hundred 'nanometers' ... a few hundreds
of 10 to the -9 . So the number in the question should be 4.10 x 10 to the -7,
not -12, and the frequency should be 731,700 GHz.
