Question

Choose the correct relation for the speed of gamma rays Vg , the speed of X-rays Vx and the speed of microwaves Vm in free space: (A) Vg>Vx>Vm (B) Vg=Vx=Vm (C) Vg < Vx < Vm (D) Vg>Vx < Vm

Tardigrade Admin · Accepted Answer

The speed of electromagnetic waves remain the same in a medium irrespective of their wavelength. All electromagnetic waves travel with the speed of light in vacuum. ∴ Vg=Vx=Vm

Q. Choose the correct relation for the speed of gamma rays $V_{g}$ , the speed of X-rays $V_{x}$ and the speed of microwaves $V_{m}$ in free space:

$V_{g} > V_{x} > V_{m}$

$V_{g} = V_{x} = V_{m}$

$V_{g} < V_{x} < V_{m}$

$V_{g} > V_{x} < V_{m}$

The speed of electromagnetic waves remain the same in a medium irrespective of their wavelength. All electromagnetic waves travel with the speed of light in vacuum.
$∴ V_{g} = V_{x} = V_{m}$

Q. Choose the correct relation for the speed of gamma rays Vg​ , the speed of X-rays Vx​ and the speed of microwaves Vm​ in free space:

Vg​>Vx​>Vm​

Vg​=Vx​=Vm​

Vg​<Vx​<Vm​

Vg​>Vx​<Vm​
