Explanation:
The correct answer for the given question is option 'B'. Let's discuss why option 'B' is the correct answer.
a) The wavelength of red light is longer than that of blue light.
This statement is true. Red light has a longer wavelength than blue light. The wavelength of red light is typically around 700 nm, while blue light has a wavelength of around 400 nm.
b) The frequency of blue light is higher than that of red light.
This statement is also true. The frequency of a wave is inversely proportional to its wavelength. Since blue light has a shorter wavelength than red light, it has a higher frequency.
c) The speed of light is the same in all media.
This statement is not true. The speed of light depends on the medium through which it is traveling. For example, the speed of light is slower in water than in air.
d) The speed of light is maximum in vacuum.
This statement is true. The speed of light in a vacuum is approximately 299,792,458 meters per second. This is commonly denoted as 'c' in physics.
In conclusion, option 'B' is the correct answer as both statements a) and b) are true.

एकल प्रतिस्थापन अभिक्रिया वह है जिसमें अधिक क्रियाशील तत्व कम क्रियाशील तत्व को उसके लवण विलयन से विस्थापित कर देता है।
लेकिन जस्ता की तुलना में तांबा आसानी से इलेक्ट्रॉनों को नहीं खो सकता है और इसके परिणामस्वरूप कोई प्रतिक्रिया नहीं होती है।
इस प्रकार कोई रंग नहीं बदलेगा क्योंकि दोनों के बीच कोई रासायनिक प्रतिक्रिया नहीं होती है।
