Answer:
Explanation:
given,
Light wave wavelength in Air, λ_(vac) = 670 nm
wavelength in transparent solid, λ= 420 nm
Refractive index of the solid
n = 1.6
a) speed of light in the solid
v = 0.625 c
b) light's frequency in the solid
frequency of light remain same when light move from one medium to another.
f is the frequency of light
f = 4.47 x 10⁻¹⁴ Hz
the light's frequency in the solid is equal to 4.47 x 10⁻¹⁴ Hz

Answer: 5.31 meters
Explanation: Use conservation of energy. Initial energy equals final energy. Initially, there is only kinetic energy (because height = 0 initially). At the end, kinetic energy equals 0 because at max height, there is max potential energy and the ball stops moving for a split second.
mgh = .5mv^2
Masses cancel out
gh = .5v^2
(9.8)(h) = .5(10.2^2)
Solve for h. h = 5.31 meters
-40 c = -40 f but k would be 233.15
