What is the wavelength in nm of a light whose first order bright band forms a

scoundrel [369]

The wavelength of the first order bright band light light is 714 nm .

Explanation:

We have to find the wavelength of the first order brightness of a light. Here we are using Huygen's principle of light.

The formula is

nλ =d sinθ

where, n is the order of maximum

λ is the wavelength of light

d is the distance between the lines on diffraction grating.

θ is the angle.

For the given equation n is 1 because the problem states that the light forms 1st order bright band

λ is unknown.

d = $\frac{1}{700,000}$ or 0.0000014 m

sin (30) = 0.5

so,

1(λ) = (0.0000014)(0.5)

= 0.0000000714

= 714 nm

Thus, The wavelength of the first order bright band light light is 714 nm .

Arrange the examples in order, starting with the object that has the least amount of energy. In each case, assume there’s no fri

Artemon [7]

First example: book, m= 0.75 kg, h=1.5 m, g= 9.8 m/s², it has only potential energy Ep,

Ep=m*g*h=0.75*9.8*1.5=11.025 J

Second example: brick, m=2.5 kg, v=10 m/s, h=4 m, it has potential energy Ep and kinetic energy Ek,

E=Ep+Ek=m*g*h + (1/2)*m*v²=98 J + 125 J= 223 J

Third example: ball, m=0.25 kg, v= 10 m/s, it has only kinetic energy Ek

Ek=(1/2)*m*v²=12.5 J.

Fourth example: stone, m=0.7 kg, h=7 m, it has only potential energy Ep,

Ep=m*g*h=0.7*9.8*7=48.02 J

The order of examples starting with the lowest energy:

1. book, 2. ball, 3. stone, 4. brick
