Dispersion of Light

Dispersion of Light and Spectrum are discussed in this Colorful video! Is White Light really white in color? How is a Rainbow formed? These are discussed in the video along with exciting experiments on Light. We look at Dispersion of Light through a glass Prism and how the VIBGYOR Spectrum is formed.

Thank You

[alondralalala]

I actually like that he doesn't rush the information and speaks slower. I am able to actually internalize every detail of what he is saying where in some youtube videos they speak so fast i have to continually stop and rewind the videos in order to take notes and catch what they've said. Very helpful.

[MuskanShaikh-wsmf]

Ans.1 (a) violet colour is deviated the most because it's speed is less in a medium other than air or vacuum.
(b) red colour is deviated the least because it's speed is more..
Ans.2 Dispersion of light is caused because different colours of white light bend at different angles. They bend at different angles because the wavelength of different colours are different. Wavelength is directly proporotional to velocity and inversely proportional to deviation. Red light has greatest wavelength as a result its velocity is more and hence deviates less. Violet light has smallest wavelength as a result its velocity is least and deviates most. Likewise different colours deviate at different angles causing dispersion.
Ans.3 1) Refraction.
2) Total internal
Reflection.
3) Dispersion

[nehemiahlayade]

Q1. Violet is the most deviated and Red is the least deviated.
Q2. The dispersion of light occurs due to the different degrees of refraction experienced by different wavelengths of light when they pass through a medium like a prism.
Q3. Dispersion, Total Internal Reflection, Refraction

[lakshsuman]

1) a) Violet
b) Red
2) The cause of dispersion of light is:
White light is a combination of seven different colors, each with a distinct wavelength and velocity.
When white light passes through a prism or another medium, it refracts or bends at different angles depending on its wavelength and velocity.
Red light has the longest wavelength and the highest velocity, so it bends the least. Violet light has the shortest wavelength and the lowest velocity, so it bends the most. The other colors bend in between.
3) Formation of the rainbow:
Light rays reach the drop near its highest point.
There is refraction first, followed by dispersion of white light into colors of different wavelengths.
Violet is the most deviated color, while red is the least deviated.
Due to the complete internal reflection that hits the drop surface, each color is refracted back into the drop when it reaches the opposite side of the drop.

[classxi-a-sujaljain]

Q1-a)violet
B)red
Q2-the speed of the light
Q3-1.dispersion of light
2.total internal reflection
3.refraction of light Ray's
For an inquisitive child these practical videos are very helpful
Thank you sir

[agastya_a]

Hello Sir,
I have the answers for your top 3 questions.
Q1.a. The color that is deviated the most is red color.
b.The color that is deviating the least is violet.

Q2.The cause of dispersion of light is refraction.

Q3.The 3 phenomenon of light that are involved in the formation of rainbow are-
~Total internal reflection (that takes place in water droplets).
~Refraction of light.
~Dispersion of light.

Thank you so much for the video Sir I hope my answers are correct;and I enjoyed the video so much. :)

[kaveridavuluri]

1) most violet
Least red
2). Speed of different colours changes in glass medium, so it results in change of angles therefore it undergoes dispersion
3) refraction,
Dispersion,
Total internal reflection (TIR(

[رانياحسين-جج]

Q1(a)violet (b)red
Q2: the cause of dispersion is the fact that white light consists of many colours with many wavelengths and speeds in medium other than air and so when white light travels from air to another medium it splits into their colours because of different refraction angle for different colours.
Q3:1-dispersion
2-total internal reflection
3-refraction

[Obsessedwithyou_]

Q.1 a) Violet deviates the most.
b) Red deviates the least.
Q.2 Refraction is the cause of dispersion of light.
Q.3 Dispersion, total internal reflection and refraction are the 3 phenomenons of light involved in the formation of Rainbow.

[sridharbonam]

1. Red, violet
2.when the light travels to different mediums like air to water or glass etc
3.total internal reflection, dispersion of light, refraction
Good teaching sir

[Siya_]

1. a) Violet b) Red
2. The splitting up of white light into seven colors on passing through a transparent medium.
3. Dispersion, Total internal reflection & refraction.

[surendrasingh]

1- a) violet b) red
2- because different colors have different frequencies
3-refraction, dispersion, total internal reflection

[hrishitasarkar]

1.(a)violet.
(b)red.
2.Dispersion of light occurs because of refraction and because the speed of different colours of light is Same in air but when it enters the prism refraction occurs as the medium is changing and also the speeds of different colours of light in prism are different so it split into seven colours.
3.▪︎Refraction of light.
▪︎Dispersion of light.
▪︎Total internal reflection of light.

[bugsbuhny]

this is the only yt video that i don't skip ads as it is the only way i can pay back for your efforts. i highly appreciate how informative and creative your teachings are. i easily understand them all. thank you, Sir!

[princesstricia]

1a. Violet
b.Red
2.When white light incident on a glass prism and crosses the boundary between two media can cause dispersion of white light
3.i. Dispersion
ii. Total internal reflection
iii. Refration

[parvrock]

This man is a blessing. He made understood the prism example which was only just recited by the other teachers.

[yasinmalik]

1Voilet deviated the most, red deviated the least.
2 difference in the speed of colours.
