The shape of the wave will be like that of a sine curve, and it will repeat periodically over a time interval.
Its wavelength will be between 400 nm and 700 nm.
We know that the intensity of light decreases as the square of the distance
from the source.
Lamp-1 is twice (2x) as far from the detector as Lamp-2 is.
If they appear equal to the detector, then Lamp-1 must be (2)² = 4 times
as bright as Lamp-2.
4 x 15 candelas = 60 candelas
Question #15).
A). is true, but has nothing to do with particle behavior
B). Diffraction is a purely wave thing, so it doesn't help.
C). is true, but doesn't say anything about particle behavior
D). is true, but isn't an indication of particle behavior.
Looks to me like NONE of the choices is any help
to suggest particle behavior.
The period of oscillation of the system is 12.56 s
Explanation:
The period of oscillation of a spring-mass system is given by
where
m is the mass attached to the spring
k is the spring constant
For the system in this problem, we have
m = 40 kg
k = 10 N/m
Substituting into the equation, we find
