JEE MAIN - Physics (2020 - 4th September Morning Slot - No. 4)
Choose the correct option relating wave lengths of different parts of electromagnetic wave spectrum:
$$\lambda $$radio waves > $$\lambda $$micro waves > $$\lambda $$visible > $$\lambda $$x-rays
$$\lambda $$visible > $$\lambda $$x-rays > $$\lambda $$radio waves > $$\lambda $$micro waves
$$\lambda $$visible < $$\lambda $$micro waves < $$\lambda $$radio waves < $$\lambda $$x-rays
$$\lambda $$x-rays
< $$\lambda $$micro waves < $$\lambda $$radio waves < $$\lambda $$visible
Vysvětlení
Decreasing order of wavelength,
Radio wave > Microwave > Infrared >
ROYGBIV(Visiable Resion) > Ultraviolet > X rays > $$\gamma $$ rays
So the correct order -
$$\lambda $$radio waves > $$\lambda $$micro waves > $$\lambda $$visible > $$\lambda $$x-rays
Radio wave > Microwave > Infrared >
ROYGBIV(Visiable Resion) > Ultraviolet > X rays > $$\gamma $$ rays
So the correct order -
$$\lambda $$radio waves > $$\lambda $$micro waves > $$\lambda $$visible > $$\lambda $$x-rays
