In the lab students determine the factor affecting the frequency of a pendulum. In the lab students determine the factor affecting the frequency of a pendulum and relate to simple harmonic motion.

New research has revealed a new technique by which scattering of sound waves from disorder in a material can be suppressed on demand. All of this, can be simply achieved by illuminating with the ...

A year after the Soviet Union tested the world’s largest thermonuclear weapon known as the Tsar Bomba. The United States conducted its own thermonuclear test in the South Pacific codenamed “Starfish ...

Using electromagnetic waves to flummox and follow smarter weapons has become a critical part of the cat-and-mouse game between Ukraine and Russia. The United States, China and others have taken note.

A team of researchers from the University of Ottawa has developed innovative methods to enhance frequency conversion of terahertz (THz) waves in graphene-based structures, unlocking new potential for ...

A LPF transmits a multicycle fundamental pulse at ω, which produces a signal at 3ω after nonlinear interactions in a graphene-based sample. The LPF and HPF consist of a superposition of four ...
