Answer:
electromagnetic waves= LIGHT, TRAVELS IN A VACUUM, VIBRATIONS IN MAGNETIC FIELD
matter/mechanical= REQUIRES A MEDIUM, SOUND, COMPRESSIONS,
both= TRANSFERS ENERGY, AMPLITUDE, FREQUENCY, WAVELENGTH,
Explanation:
electromagnetic waves don't need particles/atoms to travel through whilst matter/mechanical waves do.
Let us evaluate the given assumptions according to the kinetic theory for an ideal gas.
a.
The motion of one particle is unaffected by other particles unless the particles collide.
TRUE. The particles are in random motion unless they collide.
b.
The forces of attraction among particles keep the particles close together.
FALSE. No forces act between particles except during collision.
c.
Under ordinary conditions, forces of attraction between particles can be ignored.
TRUE.
Answer: Statement b is false because it is not an assumption.
Answer:
The value is 
Explanation:
From the question we are told that
The first amplitude of the wave is 
The first depth is 
The second amplitude is 
The second depth is 
Generally from the spatial wave equation we have
=> 
So considering the ratio of the equation for the two depth
=> 
=> 
=>
