FRAN HEATHCOTE believes that while the the Chancellor outlined some positive steps, the government does not appreciate the scale of the cost-of-living crisis affecting working-class people, whose lives are blighted by endemic low pay
WHAT if you could capture light in a box? Lasers work on that very principle. Light is a wave and any colour is described by a particular wavelength. To trap light in a box, mirrors are used, with the dimensions specially chosen so that the light can reflect off the mirrors and “resonate” at its own wavelength.
Just like a musical instrument, these resonant waves reinforce each other. For a musical instrument, these reinforced waves come out as a sound wave making a note at a particular frequency, which is related to the wavelength.
In the case of a laser, light is trapped at a high intensity, again at a singular frequency related to the wavelength of the light. Some of the light is allowed to burst out of the container, seen as a laser beam.
Neutrinos are so abundant that 400 trillion pass through your body every second. ROX MIDDLETON, LIAM SHAW and MIRIAM GAUNTLETT explain how scientists are seeking to know more about them
