Homework question answer (a). Red colour is selected for danger signals because the red colour is least scattered by by fog or smoke , hence visible from a long distance. (b) the sky appears dark in space because in the absence of atmosphere there is no scattering of light. I really like this session Thank you so much sir 👍
HW: a) because red colour has larger wavelength,hence it can travel longer distance and the person can see clearly the danger signal b) there is no atmosphere in space to scatter the light..hence space appears black in colour :)❤
HOMEWORK ANSWERS- 1) Red colour scatters less as it has the high wavelength. So red light is able to travel the longest distance through the fog, rain, and air particles. That is why the red colour is used in danger signals. 2) The sky looks dark and black instead of blue because there is no atmosphere containing air in the outer space to scatter sunlight. Therefore the sky looks dark and black there. Please tell important diagrams for biology!!!
Sure @neet_aspirant in biology diagram the major focus is on diagram based questions. You can refer to asexual mode of reproduction, male and female reproductive systems, flower, brain, neuron, and all the diagrams from life processes. We will make sure we address your concern in a session for sure. Thank you
HOMEWORK QUESTION : 1. Red colour is selected for danger signals because it is scattered the least . So, it can be seen from some distance. 2. The sky appears dark in space because there is no atmosphere there. We r very grateful to u sir for all ur efforts that u are putting for us so that we can ace our exams. Thanks a lot sir 💫💫
ANS (i)Red colour scatters the least as it has the greatest wavelength. So red light is able to travel the longest distance. That is why the red colour is used in danger signals. (ii)the sky looks dark and black because there is no atmosphere containing air in the outer space to scatter sunlight. So, there is no scattered light to reach our eyes in outer space, therefore the sky looks dark and black there.
HOME WORK ANSWERS 1.The red is least scattered by fog or smoke.Therefore it can be seen in the same colour in the same colour at a distance without scattering. 2.The sky appear dark and black in space because there is no atmosphere containing air in puter space to scatter light.Since there is no scattered light which can reach our eyes in outer space,therefore the sky looks black and dark there.
A. Red colour has the longest weve length due to which it is scatters the least and visible in even misty or smogg days. This, it is selected for danger signals . B. As there is no atmosphere in space atmospheric refraction does not occur and hence the sky appear dark in space.📚🔰📚
Homework 1) Because red is less scattered by the air molecules, it is used to indicate danger signals. By dispersing particles at smaller wavelengths, light can travel longer distances through clouds, fog, rain, etc. Rayleigh scattering occurs when the wavelength of the light is significantly smaller than the wavelength of the dispersing particles. 2) No atmosphere exists in space. Because of this, sunlight rays are not scattered by the atmosphere. As a result, astronauts perceives the sky as dark. Thank you so much sir for this wonderful session ❤🔥❤
*HOMEWORK ANS:-* Q1) Red color is selected for danger signals because it scatters the least and has longer wavelength due to which it is easy for a person to detect the color(danger signal) from far distances. Q2) The sky appears dark in space because it has no atmosphere, hence scattering of light doesn't occur there.

Good Vaishnavi, Keep Watching and Keep Learning😊
Sir in Q4 35:40 according to real diagram i) line is not correct
it goes straight "that red colour light" in diagram given below
Sir almost easy 😊 .. but which question I'm lagging there my doubts are clearified 😅😅 thank you sir❤❤

Thanks sir
This is the best video
It helps me a lot
I enjoyed it . I didn't feel bored in the whole session
Please provide us such more type of video

What is mean by presbyopia sir
Red is scattered least so deviated least so we do use as red signal
Please provide free pdfs of the session sir.. So that we will be able to study from that sir.. But the vdo was really helpful.. Thank you so much
