The correct answer is: A. Have low penetrating power.
X-rays are a type of electromagnetic radiation with a wavelength shorter than that of visible light. They are produced when high-energy electrons are accelerated and then collide with a metal target. The collision produces a shower of X-rays, which can be used to create images of the inside of the body.
X-rays have a high penetrating
power, which means they can pass through many materials, including skin and muscle. However, they are absorbed by bone, which is why X-rays are often used to diagnose bone fractures.X-rays can also be reflected or refracted, just like visible light. This is why they can be used to create images of the inside of the body.
X-rays can affect photographic plates, which is how they were first discovered.
When X-rays pass through a photographic plate, they cause the silver salts on the plate to darken. This darkening can be used to create an image of the object that was exposed to the X-rays.In conclusion, X-rays have a high penetrating power, can be reflected or refracted, and can affect photographic plates. Option A is the only option that is not true about X-rays.
