A wave has a wavelength 10-3 nm. (a) Name the wave. (b) State its one property different from light.

Answer

**Step-by-Step Solution:**

**Step 1: Identify the type of wave based on the given wavelength.**
- The wavelength given is \(10^{-3}\) nm. This wavelength is extremely short, which is characteristic of gamma rays.

**Conclusion for Step 1:** The wave is a gamma ray.

**Step 2: State one property of gamma rays that is different from light.**
- One significant property of gamma rays is their strong penetrating power. Unlike visible light, which can be easily blocked by opaque materials, gamma rays can penetrate through various substances, including human tissue and several centimeters of lead.

**Conclusion for Step 2:** Gamma rays have strong penetrating power compared to normal light.

**Final Answer:**
(a) The wave is a gamma ray.
(b) One property different from light is that gamma rays have strong penetrating power.
