Question

Rank the following waves from fastest to slowest ,Sound waves ,water waves ,light waves.

Answer 1

1. The decreasing order of the waves according to the speed is as follows
2. A) light waves :Light waves travels with a speed of about 3,00,000 $\frac{km}{s}$.
3. Light waves can travel faster than any other waves .
4. B) Sound waves :The speed of sound waves is 343 $\frac{m}{s}$ at ${20}^{o}C$.
5. C) Water waves : Speed of water wave depends upon few factors .
6. These waves discharge outwards ,generating impulse at speed of up to 500 miles (800 km )per hour. Reaching maximum height of 100 feet (30 metres )near coastal areas.

Hence, waves from fastest to slowest is Light waves > sound waves > water waves .
