Answer:
In a coiled spring, the particles of the medium vibrate to and fro about their mean positions at an angle of
A. 0° to the direction of propagation of wave
Explanation:
The waveform of a coiled spring is a longitudinal wave, which is made up of vibrations of the spring which are in the same direction as the direction of the wave's advancement
As the coiled spring experiences a compression force and is then released, it experiences a sequential movement of the wave of the compression that extends the length of the coiled spring which is then followed by a stretched section of the coiled spring in a repeatedly such that the direction of vibration of particles of the coiled is parallel to direction of motion of the wave
From which we have that the angle between the direction of vibration of the particles of the coiled spring and the direction of propagation of the wave is 0°.
In sulfur dioxide, there are 2 oxygen atoms and 1 sulfur atom. As there are 32g of sulfur and 32g of oxygen, that would mean that each oxygen atom would weigh about 16g. Given that, the mass of a single sulfur atom is twice that of a single oxygen atom.
Answer:
Here are the em radiation in order of increasing frequency from left to right. Also, the wavelength decreases as we move from left to right.
Radio, micro, infrared, visible, ultraviolet, x-ray and gamma ray.
According to quantum physics, you use E = hf ( where E = energy of a photon of a type of em wave, h is Planck constant and f is frequency of that photon ) to find the energy.
From here you can see that as we move from left to right, energy increases because frequency increases.
