The Mystery of Dark Matter Clarified—a Little

That means there’s still hope for a dark horse in the dark matter sweepstakes ... slightly blocking the light they emit. But while planets marginally dim the light of a star, a black hole moving in front of it should have the opposite effect.Physicist suggests speed of light might be slower than thought

This image shows the remnant of Supernova 1987A seen in light ... theorised 80 years ago. Here's a question… how long does it take sunlight to reach Earth? This sounds like a strange question, but think about it. Sunlight travels at the speed of light.It's a Molecule. No, It's More Like a Wave.

This means that something with a tiny mass moving ... an electron has a relatively large mass and momentum. This means that the wavelength of an electron, according to de Broglie's formula, is only about one-10,000th the wavelength of a photon of light ...CBSE class 12th Physics - Photo electric effect

In an experiment on photoelectric effect, the slope of the cut-off voltage versus frequency of incident light ... is the de Broglie wavelength of (a) a bullet of mass 0.040 kg travelling at the speed of 1.0 km/s, (b) a ball of mass 0.060 kg moving at ...And Let There Be "Molecules" of Light

It is an area around a moving electric ... that the energy of the electron depends on the wavelength of light. Schrodinger studied that light was coherent. This proves that light has the property of superposition. De Broglie used the concept of frequency ...
