- Ritter used silver chloride which darkens on exposure to light. Rate of reaction increased from red to violet. Fastest reaction was just beyond red.
- Similarities Both transverse. Can travel through empty space. Travel at 300,000,000m/s
- Differences. X- rays higher freq lower lambda. Ionizing ability. Penetrating power.
- Alpha=Strong Beta= Weak Gamma= very weak
- ionizing radiation has sufficient energy to remove electrons from atoms
- X-rays absorbed by dense materials. Pass through less dense materials and darker photographic film.
- Gamma can kill cells/bacteria/viruses. Cancer cells more easily damaged than healthy cells
