A 460 nm monochromatic light is split into two beams. The two beams arrive at a point on a screen with a path difference of 920n

VladimirAG [237]

Answer:

phase difference $\Delta \Phi = 12.566$

Explanation:

Phase difference is expressed as $\Delta \Phi$

$\Delta \Phi =\frac {2\pi}{\lambda} \Delta X$

Where,

$\Delta \Phi$ = phase difference

$\lambda$ wavelength = 460nm

$\Delta X$ path difference = 920 nm

$\Delta \Phi =\frac {2\pi}{460} *920 = 4\pi$

therefore

phase difference $\Delta \Phi = 12.566$

Explain why you poured the ester into water before you identify the smell ?

serious [3.7K]

You will pour the ester into water before you identify the smell because the smell is mixed with the smell of a carboxylic acid. with the use of the water the carboxylic acid will dissolved in it, while the ester will form a layer because it is not soluble in water, and you will smell it clearly

When the electron in a hydrogen atom moves from n = 6 to n = 1, light with a wavelength of ________ nm is emitted?

Oduvanchick [21]

First we find the energy level with the following formula, where a is the energy level, n1 is the final energy level, n2 is the starting energy level and r is Rydberg's constant in Joules
$a = r \times ( \frac{1}{n1} - \frac{1}{n2} )$
We insert the values

$a = 2.18 \times {10}^{ - 18} \times ( \frac{1}{ {1}^{2} } - \frac{1}{ {6}^{2} } )$
$= 2.12 \times {10}^{ - 18}$
The wavelength is found with this formula, where h is Planck's constant and c is the speed of light
$wavelength = \frac{h \times c}{a}$
Finally we insert the values
$\frac{6.626 \times {10}^{ - 34} \times 3 \times {10}^{8} }{2.12 \times {10}^{ - 18} } = 9.376 \times {10}^{ - 8}$
Which is the same as 93.8 nm

For every 120 joules of energy input a car wastes 85 joules , find the useful energy output of the car ?

Tamiku [17]

Answer:

35 Joules

Explanation:

Applying

Input Energy(Q) = Useful energy output(U)+Wasted Energy(W)

Q = U+W.............................. Equation 1

Make U the subject of the equation

U = Q-W................... Equation 2

From the question,

Given: Q = 120 Joules, W = 85 Joules

Substitute these values into equation 2

U = 120-85

U = 35 Joules

With what type of electromagnetic radiation would you observe:

Viefleur [7K]

Answer:

Green part of the visible spectrum.

X ray part of the electromagnetic spectrum.

Infrared part of the electromagnetic spectrum.

Explanation:

Wien's displacement law

$\lambda_{max}=\frac{b}{T}$

Where, b = Wien's displacement constant = 2.898×10⁻³ mK

T = Temperature in kelvin

$\lambda_{max}=\frac{2.898\times 10^{-3}}{5800}\\\Rightarrow\lambda_{max}=0.499\times 10^{-6}=0.5\mu m=500\ nm$

So, the wavelength would be of around the green part of the visible spectrum.

$\lambda_{max}=\frac{2.898\times 10^{-3}}{1\times 10^6}\\\Rightarrow\lambda_{max}=2.898\times 10^{-9}=2.898\ nm$

So, the wavelength would be of around the X ray part of the electromagnetic spectrum.

Human body temperature = 37°C = 37+273.15 = 310.15 K

$\lambda_{max}=\frac{2.898\times 10^{-3}}{37+273.15}\\\Rightarrow\lambda_{max}=\frac{2.898\times 10^{-3}}{310.15}\\\Rightarrow\lambda_{max}=9.34\times 10^{-6}=934\ nm$

So, the wavelength would be of around the Infrared part of the electromagnetic spectrum.
