Lambert's laws (J.H. Lambert):
Lambert's first law
The illuminance on a surface illuminated through light falling onto it perpendicularly from a point source is proportional to the inverse square of the distance among the surface and the source.
Lambert's second law
If the rays meet the surface at a particular angle, then the illuminance is proportional to the cosine of the angle along the normal.
Lambert's third law
The luminous intensity of light reduced exponentially through distance as it travels via an absorbing medium.
A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly over the rod. The magnetic field half way among the axis o
so we just started physics in grade 10, and i dont understand to much of it.. could you help me better understand it? and help me understand what i should expect?
explain the pitch of sound and also explain is the ghosts come in the category of matter? is the sound is the form of wave? explain sound,intensity,types,loudness of sound, quality
The equation of reflected wave for soft boundary: y(x.t)=A cos[(wt-kx)] The equation of reflected wave for rigid boundary: y(x.t)=A cos[(wt+kx)] where A=amplitude of the wave
In this problem we will consider a vapor fluid interface on top of a solid surface. A schematic is shown below: This is a zoomed-in picture of the edge of a liquid droplet
