प्रश्न
Two waves A and B have wavelength 0.01 Å and 9000 Å respectively.
- Name the two waves.
- Compare the speeds of these waves when they travel in vacuum.
उत्तर
- A - gamma rays, B - infrared radiation.
- The ratio of the speeds of these waves in a vacuum is 1:1, as all electromagnetic waves travel at the speed of light in a vacuum.
