Answer:
t = 9.16 10⁻⁸ m
Explanation:
In this exercise we fear a case of interference by reflection,
We have two aspects
* when the light ray passes from the air to the TiO2 that has a higher refraction start, the reflected ray has a phase change of 180º
* when the beam is inside the material its wavelength changes
λₙ = λ₀ / n
with these two done the equation for destructive interference remains
2t = m λₙ
2nt = m λ₀
They ask us for the thickness t of the film for m = 1
t = m λ₀ / 2n
let's calculate
t =
t = 9.16 10⁻⁸ m

An object moving with constant speed can be accelerated if direction of motion changes. For example, an object moving with a constant speed in a circular path has an acceleration because its direction of motion changes continuously.

To solve this problem we will apply the concepts related to the kinematic equations of linear motion. For this purpose we will define the speed as the distance traveled in a given period of time. Here the distance is equivalent to the orbit traveled around the earth, that is, a circle. Approaching the height of the aircraft with the radius of the earth, we will have the following data,
The circumference of the earth would be
Velocity is defined as,
Here, then
Therefore will take s or 506 hours, 19 minutes, 17 seconds
