- Q3What is the unit of amplitude?MetersWattsSecondsHertz30s
- Q4What is the formula for calculating the speed of a wave?Speed = Frequency / WavelengthSpeed = Frequency + WavelengthSpeed = Frequency x WavelengthSpeed = Wavelength / Frequency30s
- Q5What type of wave is visible light?Electromagnetic waveLongitudinal waveMechanical waveTransverse wave30s
- Q6What is the unit of frequency?WattMeterNewtonHertz30s
- Q7What is the formula for wavelength?Wavelength = Speed + FrequencyWavelength = Speed / FrequencyWavelength = Speed x FrequencyWavelength = Speed - Frequency30s
- Q8In the GCSE ripple tank required practical, what is the purpose of using a stroboscope?To measure the amplitude of the wavesTo observe the stationary wave patternTo determine the speed of the wavesTo calculate the frequency of the waves30s
- Q9In the GCSE ripple tank required practical, what is the purpose of using a ruler?To measure the wavelength of the wavesTo determine the speed of the wavesTo control the depth of the waterTo calculate the frequency of the waves30s
- Q10Which of the following factors affects the wavelength of water waves in the GCSE ripple tank required practical?Frequency of the wavesAmplitude of the wavesDepth of the waterSpeed of the waves30s
- Q11In the GCSE ripple tank required practical, what is the purpose of using a frequency generator?To measure the amplitude of the wavesTo determine the speed of the wavesTo control the frequency of the wavesTo observe the stationary wave pattern30s
- Q12What is the purpose of the lamp in the GCSE ripple tank required practical?To illuminate the waves producedTo determine the speed of the wavesTo observe the stationary wave patternTo measure the amplitude of the waves30s
- Q13What is the purpose of using a white card in the GCSE infrared required practical?To absorb infrared radiationTo emit infrared radiationTo block infrared radiationTo reflect infrared radiation30s
- Q14What is the relationship between the temperature of an object and the amount of infrared radiation it emits?The temperature has no effect on the amount of infrared radiation emittedThe higher the temperature, the less infrared radiation it emitsThe higher the temperature, the more infrared radiation it emitsThe temperature determines the color of the infrared radiation30s
- Q15What is the purpose of using a black object in the GCSE infrared required practical?To emit infrared radiationTo block infrared radiationTo absorb infrared radiationTo reflect infrared radiation30s
