Question

What is the ratio of speed of infrared and ultraviolet radiations in vacuum?

Answer 1

1. Electromagnetic waves are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum.
2. Velocity of each wave in vacuum or free space is the same.
3. The speed of the ultraviolet rays in a vacuum is $3\times {10}^{8}m/s$.
4. The speed of the infrared rays in a vacuum is $3\times {10}^{8}m/s$.
5. The ratio of the speed of infrared rays and ultraviolet rays in a vacuum can be calculated as:

$\frac{\mathrm{Speed}\mathrm{of}\mathrm{UV}\mathrm{rays}\mathrm{in}\mathrm{vacuume}}{\mathrm{Speed}\mathrm{of}\mathrm{infrared}\mathrm{rays}\mathrm{in}\mathrm{vacuum}}=\frac{3\times {10}^8\mathrm{m}/\mathrm{s}}{3\times {10}^8\mathrm{m}/\mathrm{s}}$

$\frac{\mathrm{Speed}\mathrm{of}\mathrm{UV}\mathrm{rays}\mathrm{in}\mathrm{vacuume}}{\mathrm{Speed}\mathrm{of}\mathrm{infrared}\mathrm{rays}\mathrm{in}\mathrm{vacuum}}=\frac{1}{1}$

So, the ratio of the speed of infrared and ultraviolet rays in a vacuum is $1:1$.
