The 630 nm light from a helium neon laser irradiates a grating. The light then falls on a screen where the first bright spot is

mafiozo [28]

Answer:

The second wavelength is 482 nm.

Explanation:

Given that,

Wavelength = 630 nm

Distance from central maxim = 0.51 m

Distance from central maxim of another wavelength = 0.39 m

We need to calculate the second wavelength

Using formula of width of fringe

$\beta=\dfrac{\lambda d}{D}$

Here, d and D will be same for both wavelengths

$\lambda$ = wavelength

$\beta$ = width of fringe

The width of fringe for first wavelength

$\beta_{1}=\dfrac{\lambda_{1} d}{D}$ ....(I)

The width of fringe for second wavelength

$\beta_{2}=\dfrac{\lambda_{2} d}{D}$ ....(II)

Divided equation (I) by equation (II)

$\dfrac{\beta_{1}}{\beta_{2}}=\dfrac{\lambda_{1}}{\lambda_{2}}$

$\lambda_{2}=\dfrac{630\times10^{-9}\times0.39}{0.51}$

$\lambda_{2}=4.82\times10^{-7}$

$\lambda=482\ nm$

Hence, The second wavelength is 482 nm.

Think about what subsequently happens to the ketchup, which is initially at rest, and use newton's first law to explain why this

Vika [28.1K]

Newton's first law of ketchup is if the bottle of ketchup is smacked upward, the contents (the ketchup) will tend to remain in place, and it will be closer to the opening in the bottle.

<h3>Further explanation </h3>

If we are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle a upward smack which force the bottle rapidly upward.

Newton first law said that every object tries to continue in its state of rest or uniform motion unless an external force acted upon it (In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force). Newton first law describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.

Inertia explained by Sir Isaac Newton in his first law of motion (Newton law of motion). The law states that an object at rest stays at rest and an object continues its state of motion until an external force acts on it. The examples are one's body movement to the side when a car makes a sharp turn
