    আগের উত্তরে আমি শুধু ব্যাখ্যা করতে চেয়েছিলাম । কিন্তু, এখন সরাসরি উত্তর দিচ্ছিঃ Listed from longest to shortest wave length:

    ১ radio waves

    ২ infrared radiation

    ৩ ultraviolet radiation

    ৪ x-ray radiation

    ভালো থাকবেন ।

    Electromagnetic Waves have different wavelengths

    When you listen to the radio, watch TV, or cook dinner in a microwave oven, you are using electromagnetic waves.

    Radio waves, television waves, and microwaves are all types of electromagnetic waves. They differ from each other in wavelength. Wavelength is the distance between one wave crest to the next.

    Waves in the electromagnetic spectrum vary in size from very long radio waves the size of buildings, to very short gamma-rays smaller than the size of the nucleus of an atom.

    Did you know that electromagnetic waves can not only be described by their wavelength, but also by their energy and frequency? All three of these things are related to each other mathematically. This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave. The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
