Question

The speed of sound is $330m{s}^{-1}$ and that of light is $3\times {10}^{8}m{s}^{-1}$. The ratio of speed of sound to that of light is approximately $1:{10}^6$.

• A. True
• B. False

Answer 1

The correct option is A True

Speed Of Sound$\left(V\right)$ is, $330m/s$ and that of Light$\left(U\right)$ is, $300\ast {10}^{6}m/s$

Now we have to find, $V:U$ and i.e., $V:U=330:300\ast {10}^6\cong 1:{10}^6$ , because in comparison to $U$(Speed of Light) , Speed of Sound$\left(V\right)$ is comparetively very $small$.

So, we can assume that, Speed of Sound$\left(V\right)$ is $300m/s$ in comparison to that of Speed of Light$\left(U\right)$ that is $3\ast {10}^6$

Hence, $V:U=1:{10}^6$

Hence, it is True.

Option A is correct
