What is the longest wavelength that can be observed in the third order for a transmission grating having 5200 slits/cm?
Anarel [89]

Answer:

641 nm.

Explanation:

Given that,

A transmission grating has 5200 slits/cm.

We need to find the longest wavelength that can be observed in the third order. Using grating equation as follows :

d\sin\theta=m\lambda ...(1)

d is slit spacing

No fo slit per unit length :

N={5200}\ slit/cm\\\\=520000\ slits/m

We know that, N = 1/d

For longest wavelength, θ = 90°

From equation (1)

\dfrac{\sin\theta}{m\lambda}=\dfrac{1}{d}\\\\520000=\dfrac{\sin(90)}{3\lambda}\\\\\lambda=\dfrac{1}{520000\times 3}\\\\=6.41\times 10^{-7}\ m\\\\=641\ nm

Hence, the longest wavelength in third order for a transmission grating is 641 nm.

An earthquake produces longitudinal P waves that travel outward at 8000 m/s and transverse S waves that move at 4500 m/s. A seis
vivado [14]

Answer:

1234285.7 m or 1234.3 km

Explanation:

Let the distance be d, the time taken by P waves be t_P and the time taken by the S waves be t_S.

\text{Velocity}\dfrac{\text{Distance}}{\text{Time}}

\text{Time}\dfrac{\text{Distance}}{\text{Velocity}}

For the P waves,

t_P=\dfrac{d}{8000}

d=8000t_P

For the S waves,

t_S=\dfrac{d}{4500}

d=4500t_S

Equating the d,

8000t_P=4500t_S

Divide both sides of the equation by 500 to reduce the terms.

16t_P=9t_S

Since S waves arrive 2 minutes (= 120 seconds) after P waves,

t_S-t_P=120

t_S=120+t_P

Substitute this in the equation of the distance.

16t_P=9(t_P+120)

16t_P=9t_P+1080

7t_P=1080

t_P=\dfrac{1080}{7}

Substitute this in the equation for d involving t_P.

d=8000t_P

d=8000\times\dfrac{1080}{7}

d=1234285.7 \text{ m }= 1234.3 \text{ km}

Do magnets have to touch each other in order to experience a magnetic<br> force? Explain
tiny-mole [99]
Magnets don’t need to touch each other in order to be magnetic because all objects have an attraction however, the closer the magnets get, the more magnetic it is.
