A thin film of alcohol (n = 1.36) lies on a flat glass plate (n = 1.51). When monochromatic light, whose wavelength λ can be cha
Shkiper50 [21]

Answer:

The thickness of the film, t = 470.59 nm

Explanation:

\lambda_{film} = \frac{\lambda}{n_{film} }

For constructive interference, the net phase change, \phi = \phi_{2} -  \phi_{1} = 2\pi m_{1}

Then the thickness,  t = 0.5 \lambda_{film} m_{1}

m₁ = 1,2,3........

t = 0.5\frac{\lambda_{1} }{n_{film} } m_{1}..............(i)

For destructive interference, the net phase change is  \phi = \phi_{2} -  \phi_{1} = 2(m_{2} + 1)\pi

m₂ = 1,2,3........

thickness, t = 0.5\frac{\lambda_{1} }{n_{film} }(2 m_{2}+1)..............(ii)

Equating (i) and (ii)

0.5\frac{\lambda_{1} }{n_{film} } m_{1} = 0.5\frac{\lambda_{1} }{n_{film} }(2 m_{2}+1)

\frac{2m_{2} + 1}{2m_{1} } = \frac{\lambda_{1} }{\lambda_{2}} = \frac{640}{512}

\frac{2m_{2} + 1}{2m_{1} } = 1.25.............(iii)

From (iii), When m₁ =2, m₂ = 2

The thickness , t = 0.5\frac{\lambda_{1} }{n_{film} } m_{1} then becomes

t = 0.5\frac{640}{1.36} *2

t = 470.59 nm

Feliz [49]

Answer:

This question is unclear but the answer is:

the color of the con

Explanation:

In an experiment, the independent variable is the variable that is changed or manipulated by the experimenter to achieve a measurable response.

In this experiment which involves a student that notices that wearing care colors insight makes him feel warmer se. He decides to conduct an experiment by manipulating the colors of the cares, hence, the color of the con is the independent variable.

Describe the rise and fall of a thrown basketball by using the concepts o kinetic energy and potential energy
denpristay [2]

Explanation:

The kinetic energy is due to the motion of the object.

The potential energy is due to the position of the object.

When a basketball is thrown upward then the kinetic energy decreases and the potential energy will be maximum when it will reach its maximum height.

When it starts falling then potential energy starts decreases due to the decrease in the height and the kinetic energy starts increases.
