A grating has 460 rulings/mm. What is the longest wavelength for which there is a 6.0th-order diffraction line
mestny [16]

Answer:

λ = 3.62 x 10⁻⁷ m = 362 nm

Explanation:

The grating equation gives the relationship between the wavelength, the diffraction line order and the diffraction angle. The grating equation is written as follows:

mλ = d Sinθ

where,

m = order of diffraction = 6

λ = longest wavelength = ?

d = 1/(460 rulings/mm)(1000 mm /1 m) = 2.17 x 10⁻⁶ m/ruling

θ = Diffraction angle = 90° (for longest wavelength)

(6)λ = (2.17 x 10⁻⁶ m/ruling) Sin 90°

λ = (2.17 x 10⁻⁶ m/rulings)/6

<u>λ = 3.62 x 10⁻⁷ m = 362 nm</u>

Answer:

1. Decrease

2. Decrease

3. Stay the same

Explanation:

1. The more predators there are that eat the prey(cricket/frog), the less prey there will be.

2. The more the pollution effects them negatively, the more the population will die off.

3. The decrease of food may kill the population, but the increase of food does not effect the birth rate of the population.

A rock falls for 1.43 seconds how far did it fall? The falls's velocity is an acceleration of -9.81 m/s2
BartSMP [9]

Answer:

s = -0.100 \  m

Explanation:

Generally from kinematics equations we have that

          s = ut + \frac{1}{2}gt^2

Here u is the initial velocity of the rock and the value is  0 m/s given that there was no information that it was in motion before the fall

substituting 1.43 s for t and -9.8m/s^2 for g we have that

         s = 0 *1.43 + \frac{1}{2}(-9.8)*(0.143)^2

=>     s = -0.100 \  m

The negative sign show that the displacement is in the direction of the negative y-axis
