What causes dispersion of light?

1 answer:

7 0

Dispersion occurs due to the different degrees of refraction experienced by different colours of light. Light of different colours may travel with the same speed in a vacuum, but they travel at different speeds in some refracting medium. The speed of violet light is relatively lower than that of red light.

Raw sewage is raised vertically by 5.49m in the amountof

uranmaximum [27]

Answer:

P = 1235.7646 W

Explanation:

Given data:

height of raised sewage = 5.49 m

rate of sewage =1.89*10^6 lt/day

density of sewage = 1.050 kg/m^3

power is written as

$P = \frac{work}{time}$

work = m g h

$m - mass = ( \rho V)$

h -height

mass lifted per day $= ( 1.89*10^6)(1.050)$

= 1984500 kg

time = 24 hours* 3600 seconds per hour

power $P = \frac{( 1984500)(9.8)( 5.49)}{(24)(3600)}$

P = 1235.7646 W

An aurora occurs when?

Vinil7 [7]

energetic electrically charged particles (mostly electrons) accelerate along the magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the atoms to give off light.
