What is the relationship between speed velocity and acceleration?
What is the relationship between speed velocity and acceleration? Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of […]

Where does the energy of redshifted photons go?
Where does the energy of redshifted photons go? Where does the energy go when light is redshifted? It doesn’t go anywhere. Let’s say we’re motionless with respect to some source which is emitting a stream of photons. We agree that the photons have some energy E=hf. How much energy is lost when light hits a […]

What can a shadow tell you about the size of the source of light?
What can a shadow tell you about the size of the source of light? The location of a light source relative to the object casting shadows determines the size of the shadows. Alternatively, moving the light closer to the subject will enlarge the shadow, making the shadow much bigger than the subject itself, as shown […]
