What causes dispersion of light?​

Physics
1 answer:
AysviL [449]3 years ago
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.

How many ""accelerators"" do you have in your car? There are three ways to change the velocity of a car and there are three corr
elena-s [515]

Answer:

The three "accelerators"  are: the throttle,  the steering wheel and the brakes.

Explanation:

Acceleration means change in velocity. But this change may be in module or in direction.

Car throttle will increase the  velocity module of the car and brakes wil diminish it. On the other hand, the steering wheel will change the direction of the velocity.

Hope my answer helps you.    Have a nive day!

3. Calculate the wavelength of wave that has a frequency of 4.75 x 1012Hz.
Klio2033 [76]
  • Frequency=v=4.75×10^12Hz
  • Wavelength=?

We know

\boxed{\sf \lambda=\dfrac{C}{V}}

\\ \sf\longmapsto \lambda=\dfrac{3\times 10^8ms^{-1}}{4.75\times 10^{12}s^{-1}}

\\ \sf\longmapsto \lambda=0.631\times 10^{-4}m

\\ \sf\longmapsto \lambda=6.31\times 10^{-5}m

An athlete produced 840 watts of power in 0.6 seconds. How much work did this individual perform during the exercise
Veseljchak [2.6K]

An athlete produced 840 watts of power in 0.6 seconds. And will produce 504 joule of work did this individual perform during the exercise.

<u>Solution:</u>

we know that power is the work done completed in a given interval of time.

Power = \frac{work}{time}

also, Work = Power × Time

Work = 840 × 0.6 = 504 joule

What is Power?

  • The quantity of work that can be accomplished in a certain amount of time is measured by power.
  • Power is expressed in joules per second (J/s) this is because work is denoted by the symbol J and time by the symbol s.
  • This is the watt, which is also known as the power unit in SI (W). One joule of labor per second is equal to one watt.
  • The number of watts that a device uses is indicated on labels for lightbulbs and other small appliances like microwaves.
  • A force must be applied in order for work to be completed, and there must also be motion or displacement in the force's direction.
  • The amount of force multiplied by the distance moved in the force's direction is known as the work done by a force acting on an item. Work has no direction and only magnitude. Work is a scalar quantity as a result.
