Light bulbs, think about parallel circuits as something you plug into, so for example you plug in a tv for it to work, same with a refrigerator and Christmas lights

A light source simultaneously emits light of two wavelengths, 480 nm and 560 nm, respectively. The source is used in a double-sl

Assoli18 [71]

Answer:

0.48 cm

Explanation:

given data

wavelength = 480 nm

wavelength = 560 nm

slit spacing = 0.040 mm

distance between double slits and the screen = 1.2 m

solution

we know that (1 nm= $10^{-9}$ m)

we wil take here equation of equations of interference that is

ym = R × (m λ)/d ..........................1

here m = 2 R i.e distance of screen and slit

so put here value and we get

separation between the second-order bright fringes = 0.48 cm

If an earthquake occurred in Miami, Florida, then how long would it take for a seismic station in Seattle, Washington, to pick u

Juliette [100K]

0.017s

Explanation:

Given parameter

Distance = 5000km = 5 x 10⁶m

Unknown:

time taken = ?

Solution:

We use the normal speed equation to solve this problem as we take the speed of the wave to be 3 x 10⁸m/s.

Speed = $\frac{Distance }{Time taken}$

Inputting the parameters:

Time taken = $\frac{distance }{velocity of the wave}$

Time taken = $\frac{ 5 000000}{3 00000000}$ = 0.017s
