Hay represents two-dimensional motion
1 answer:
If a body is moving from left to right or right to left it is linear motion in x- direction. It is also called one dimensional motion.
If a body is moving up to down or down to up it is linear motion in y- direction. It is also called one dimensional motion.
But if a body is moving forward as well as downward it travels in X direction and in y direction at the same time. Such a motion is called two dimensional motion.
E.g motion of a ball.

Answer:
The possible thickness of the soap bubble =
Explanation:
<u>Given:</u>
- Refractive index of the soap bubble,
- Wavelength of the light taken,
Let the thickness of the soap bubble be .
It is given that the soap bubble appears very bright, it means, there is a constructive interference takes place.
For the constructive interference of light through a thin film ( soap bubble), the condition of constructive interference is given as:
where is the order of constructive interference.
Since the soap bubble is appearing very bright, the order should be 0, as order interference has maximum intensity.
Thus,
It is the possible thickness of the soap bubble.
