Answer:
540 nm
Explanation:
According to the question,
The refractive index of the soap bubble,
.
The thickness of the soap bubble wall is,
.
Now, for constructive interference of soap bubble.
.
Now for first order m=1.
Therfore,

Substitute all the variables in the above equation.
.
Therefore,
.
Therefore the visible light wavelength which is strongly reflected is 540 nm.
Answer:
If the object is moving with an acceleration of +4 m/s/s (i.e., changing its velocity by 4 m/s per second), then the slope of the line will be +4 m/s/s.
Explanation:
Answer:
Mechanical advantage is the measure of the force amplification achieved by using a tool , mechanical device or machine . The machine preserve the input power and supply trade off force. against movement to obtain a desired amplification in the output force .
