The line in which waves that are moving together are all in the same phase is referred to as the wave front.
For example, in a series of waves, all of the crests that are in a single line make up a single wave front. This is the case for every set of particles at the same specific point in a series of waves.
<span>a) light is a form of matter less dense
than air
b) light travels in straight lines
c) light has different
colors
d) light has different intensities and can be dim or bright
Yes, thank you for coming back and supplying the list of choices.
At the level of Physics all the way up to somewhere in college, <em>choice-a)</em>
is not a property of light.

A. long-wave radiation occupies a smaller percentage than short-wave radiation
Answer:
NO
Explanation:
Acceleration is change in velocityΔv in respect to timeΔt
so if the velocity of the car is greater than the truck it does not mean that the car acceleration is greater than the truck.
Sometimes with constant velocity it means no accelaration ,but the truck may have accelaration
so, higher velocity of the car does not mean higher acceleration
Answer:
- the angular velocity in radians per second is 125.7 rad/s
- the centripetal acceleration of the propeller tip under these conditions is 144.5 m/s
- the centripetal acceleration of the propeller tip under these conditions in multiplied of g is 1853 g
Explanation:
given information:
diameter. d = 2.30 --> r = d/2 = 2.3/2 = 1.15 m
angular velocity, ω = 1200 rev/min
- angular velocity in radians per second
ω = 1200 rev/min
= 1200 
= 125.7 rad/s
- the linear speed of its tip at this angular velocity
v = ω r
= 125.7 rad/s x 1.15 m
= 144.5 m/s
- the centripetal acceleration
a = ω^2 r, ω = 
= 
= 
= 
= 18160 
covert to multiplei of g, g= 9.8
a = 18160 /9.8 = 1853 g
