In a light wave, which properties tell you the color of light?

Alenkasestr [34]

Answer :-  In a light wave the property of wave which tells about the color of light is it's Wavelength . 

Wavelength is the distance between one crest and one through , also it is the distance after which the wave repeat itself !

It's SI unit is meter !

It is scalar quantity !!

Different Wavelength of light have different color !!

<h2>• VIBGYOR </h2>

i.e, Violent , Indigo , Blue , Green , Yellow Orange, and Red along with their shades are the colors which we can see !!

• They almost range from 400nm to 700nm ( visible range of light )

An earthquake in San Francisco produces a wave with a period of 0.80 seconds and a wavelength of 40 m., How long will it take fo

gtnhenbr [62]

Answer:

A) 3.11 Hrs

Explanation:

Wave speed is given by the formula

$Speed = \frac{wavelength}{Time\: period}$

now we will have

$speed = \frac{40}{0.80}$

$v = 50 m/s$

now the time taken by the wave to move the distance 560 km is given as

$t = \frac{distance}{speed}$

$t = \frac{560\times 10^3}{50}$

$t = 11200 s$

t = 3.11 hours
