Question

Use of red light for danger signal

Answer 1

Answer:

because red is least scattered and observed by our eyes and have more wave length.....

Answer 2

Red light have more wavelength so is less scattering and hence used for danger signal

Explanation:

• Visible light have wavelength range from approximately from 400 to 700 n m and different colors starting from violet to red ( VIBGYOR)
• Red light have approximately 700 n m wavelength which is greater among all
• Scattering of light depends inversely on the fourth power of wavelength (scattering ∝ $\frac{1}{x^{4} }$   where x is wavelength of light)
• As shown above greater is the wavelength less will be scattering hence red light is used so that it could be visible from large distance as well
