Correct: UV rays are used in sunbeds, Sound waves are longitudinal, wave speed = frequency x wavelength, Gamma waves are transverse, Gamma rays can treat cancer, Gamma rays can cause cancer, Infra red is used in cooking, UV, X and gamma are ionising, UV has higher frequency than microwaves, Infra red can cause burns, Incorrect: Sound waves are transverse, frequency = wave speed x wavelength, Gamma waves have long wavelengths, Radio waves have high frequencies, UV is the wave that transfers heat energy, EM waves travel at different speeds, 2 kHz = 200 Hz, Electromagnetic waves are longitudinal, Microwaves have higher frequencies than x rays, Radio waves can cause cancer,
