A student investigates the refraction of light through a glass block using a ray box.
Why is using a wide beam of light less likely to give accurate results than using a narrow beam?
For one angle of incidence, the student measured the angle of refraction three times. The measurements were:
23∘,27∘,25∘ 23^\circ, \quad 27^\circ, \quad 25^\circ 23∘,27∘,25∘Calculate the mean angle of refraction.
The student placed an orange filter in front of the white beam of light so that only orange light passes through. Complete the following sentence: "When white light is incident on the orange filter, all colours except for orange are ___________ by the filter."
Write down the equation which links frequency (fff), wave speed (vvv), and wavelength (λ\lambdaλ).
Light has a wave speed of 3.0×108 m/s3.0 \times 10^8 \text{ m/s}3.0×108 m/s in air. The frequency of the orange light is 5.0×1014 Hz5.0 \times 10^{14} \text{ Hz}5.0×1014 Hz. Calculate the wavelength of this orange light in air.
