The distance from peak to peak is, Frequency, Wavelength, Amplitude, Velocity, Time period, The distance from mid line to peak is, Frequency, Wavelength, Amplitude, Velocity, Time period, This is measured in hertz and tells us how many waves pass in a second, Frequency, Wavelength, Amplitude, Velocity, Time period, This tells us how long it takes for one wave. It is measured in seconds, Frequency, Wavelength, Amplitude, Velocity, Time period, Velocity , Has magnitude only, Has direction only, Is a vector, Has magnitude and direction, Is a scalar, Light waves are, Longitudinal , Transverse, Sound waves are, Longitudinal , Transverse, Glass is more dense than air, True, False, The bending of light is called, Reflection, Transmission, Refraction, Refractive index, Velocity = frequency x wavelength so frequency is equal to, Velocity x wavelength, Wavelength/velocity, Velocity/wavelength, Refraction happens because, Light changes speed when it enters a new medium, Light is reflected at a boundary , Light changes frequency when it enters a new medium, The incident ray is , The ray travelling in the new medium (glass block), The light travelling from the ray box, The light emerging from the other side of the block, The refracted ray is , The ray travelling in the new medium (glass block), The light travelling from the ray box, The light emerging from the other side of the block, The equipment we use to measure angles, Ruler, Tape measure, Protractor, A balance, Wavelength is measured in, cm, mm, m, Km.
