When hydrogen is heated or subjected to an electric discharge, it emits light with specific visible wavelengths. A diffraction g
BartSMP [9]

To solve this problem we will apply the concepts related to the double slit-experiment. For which we will relate the distance between the Slits and the Diffraction Angle with the order of the bright fringe and the wavelength, this is mathematically given as,

d sin\theta = m\lambda

Here,

d = Distance between Slits

m = Order of the fringes

\lambda = Wavelength

\text{Spacing between adjacent lines} = d = 4926nm

\text{Wavelength of light} = \lambda = 656nm

Rearranging to find the angle,

sin\theta = \frac{m\lambda}{d}

\theta = sin^{-1}(\frac{m\lambda}{d})

\theta = sin^{-1}(\frac{(4)(656*10^{-9}m)}{4926*10^{-9}m})

\theta = 32.19\°

Therefore the angle that the fourth order bright fringe occur for this specific wavelenth of light occur is 32.19°

My answers would be as follows:

<span>You step on the scale and notice that you have lost five pounds. Which of the following has changed?


B) Only your weight changed since mass is conserved. It cannot be destroyed or created.


How could you increase the mass of a wooden block?

D) None of the above. Mass cannot be created so the mass will stay the same it will only be the weight you can increase depending on the acceleration.


If you went to the moon, how would your mass change relative to your mass on Earth?

A) It would be the same on the moon as on Earth. Mass will be the same. It is weight that will change since the gravitational acceleration in the moon is different as that to the earth.
