When light wavelengths hit the retina, we can see colors, mostly we see light because it bounces off surfaces, and that gives them their color.
So, the blank could be "light of wavelengths".
Mantle I think idrk cuz of erosion
Answer:
20. This is a transverse wave.
21. a is a Crest
b is the wavelength
c is the amplitude
d is the trough
e isthe amplitude
f is the wavelength
g is time
Explanation:
Answer:
0.25 m/s
Explanation:
Average velocity = change in displacement / change in time
v = (1.5 m − 2.5 m) / (6 s − 2 s)
v = -0.25 m/s
The average speed is 0.25 m/s.
Answer:
Density is an important physical property of matter. It reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter has greater density.
