Electromagnetic radiation (UV, X-rays, gamma)

Light is one member of a family of electromagnetic rays, in order: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays.

The idea, in English

Light is one member of a family of electromagnetic rays, in order: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma rays. From radio waves to gamma rays the frequency and energy rise and the wavelength falls; X-rays and gamma rays are highly penetrating (gamma the most), so they are used to see inside objects (X-ray screens, checking welds) and to treat tumours.

Explain in Egyptian Arabic

الضوء واحد من عيلة الـ electromagnetic rays، وترتيبها كده: radio waves، microwaves، infrared، visible light، ultraviolet، X-rays، gamma rays. وإنت ماشي من الـ radio waves لحد الـ gamma rays، الـ frequency والـ energy بيزيدوا والـ wavelength بتقل. والـ X-rays والـ gamma rays عندهم penetrating power عالية (والـ gamma أعلاهم)، عشان كده بنستخدمهم عشان نشوف جوه الأجسام (شاشات الـ X-ray وفحص اللحامات) وفي علاج الأورام.

Common misconceptions

  • Gamma rays are particles like alpha and beta.

    No. Gamma rays are not particles like alpha and beta. They are electromagnetic rays, in the same family as light, at its high-energy end, and they have a very high penetrating power.

    Explain in Egyptian Arabic

    لأ، الـ gamma rays مش particles؛ دي electromagnetic rays زيها زي الضوء.

  • Only visible light is electromagnetic radiation.

    No. Visible light is one member of the electromagnetic family; radio waves, microwaves, infrared, ultraviolet, X-rays and gamma rays are electromagnetic radiation too. Visible light is simply the part our eyes can see.

    Explain in Egyptian Arabic

    الـ visible light عضو واحد من عيلة الـ electromagnetic radiation؛ الـ radio waves والـ microwaves والـ infrared والـ ultraviolet والـ X-rays والـ gamma rays منها هي كمان. الفرق إن عينينا بتشوف الجزء الـ visible لوحده.
