A ripple tank can be used to investigate the frequency close frequencyThe number of waves produced each second. The unit of frequency is hertz (Hz)., wavelength close wavelengthThe length of a single ...

The questions in this quiz are suitable for GCSE physics students who are studying reflection of waves and refraction of waves. If you struggled with the quiz, don't panic - we've got you! You can ...

The first law of refraction states that the incident rays, refracted rays, and the normal to the interface at the point of incidence, all lie in the same plane. The ratio of the sine of the angle of ...

When light travels from one substance to another, such as from air to water, it can appear bent due to refraction. This occurs because light travels at different speeds in different materials. When ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...
