Imagine the door to a theatre is opened and you are standing outside. How is it possible that you can hear the sound of the movi
e or play even if you cannot see the screen or stage ? A) reflection only happens with sound waves not waves of light so the sound waves bounce out to your ears.
B) the sound waves refract as they move from one medium to another
C) the darkness in the theatre absorbed light but not sound so you can hear
D) the sound waves diffract much more than the light waves so try bend and spread as they move through the doorway.
Imagine the door to a theatre is opened and you are standing outside. You can hear the sound of the movie or play even if you cannot see the screen or stage because <span>the sound waves diffract much more than the light waves so try bend and spread as they move through the doorway. The answer is letter D</span>
What material structure explanation lies behind the fact that the propagation velocity of longitudinal waves is the lowest in gases and the highest in solids?
1. Find the equation of eht maximal friction force:
The maximal friction force is given by the equation , where μs is the static friction coefficient, m is the car´s mass and g is the gravitational force.
2. Replace values in the equation to find the answer:
The photosynthetic wave interaction between visible light and a photosensitive part of a plant is very important t how plants use light to grow. The frequency range and intensity levels of this light, I don't know.
