Which type of radiation emitted by radioactive nuclei is the slowest moving and least penetrating?

Which of the following statements about gamma rays is incorrect?Gamma rays are used in both medical imaging and radiotherapyGamma rays are produced when there are changes to the nuclei of atomsGamma rays can penetrate the body and can damage, mutate or kill cellsWhen a gamma ray is emitted, the amount of nuclear energy stored within a nucleus increases2Which of the following statements about x-rays is incorrect?X-rays are the second shortest-wavelength type of wave on the electromagnetic spectrum (only gamma rays have shorter wavelengths than x-rays)X-rays are used in both medical imaging and medical treatmentX-rays are produced by the rapid deceleration of free electrons and by changes in the organisation of the electrons that orbit the nuclei of atomsX-rays are absorbed effectively by soft body tissue but pass easily through bone3Which of the following types of electromagnetic radiation has the lowest frequency?Radio wavesMicrowavesUltravioletVisible light4In the visible spectrum, which colour lies between blue and violet?LilacPinkUltravioletIndigo5Which of the following does NOT involve the use of infrared waves?RadiotherapyRemote controlsCookersFibre-optic communications6What a control variable?The variable which is measured in an investigationThe variable which is changed in an investigationA variable which is more important than (at least some of) the other variables in an investigationA variable that is kept constant in an investigation
