The table shows the speed and wavelength of yellow light in air. The refractive index at the air glass boundary is 1.52. (i) Calculate the frequency, in THz, of yellow light in air. Record your answer in the table. [1] (ii) Complete the table for yellow light in glass. (b) A stud…
A student carries out an experiment to determine the speed v of sound in air. The student forms stationary sound waves in a resonance tube with water at the bottom as shown in Fig. 7.1. Fig. 7.1 The depth of the water is d. Sound is produced by a signal generator connected to a l…
(a) A student investigates the potential difference across a light emitting diode (LED). The student records the wavelength $ \lambda $ of the light emitted from the LED from a datasheet. The student measures the minimum potential difference V across the LED when the LED first st…
