Explanation:
Since red, green, and blue are primary colors of light, yellow is the only option which is not. So, yellow is not a primary color of light.

Answer:
The minimum distance moved by mirror is 125 nm
Explanation:
Given:
Wavelength of light
m
Here given in question, spot of constructive interference change to a destructive interference.
Hence minimum distance moved by one of mirror is given by,
Where
distance moved by mirror



Therefore, the minimum distance moved by mirror is 125 nm
Answer:
Explanation:
The original frequency of sound f₀
The apparent frequency of sound fa
For apparent frequency the formula is
fa =
, v is velocity of jumper which increases as he goes down .
Beat frequency
= fa - f₀
= 
= 
since v is very small in comparison to V , velocity of sound , in the denominator , v can be neglected.
beat frequency = 
v , the velocity of jumper will go on increasing as long as net force on the jumper is positive or
mg > kx where x is extension in the cord and k is its force constant . Below this point kx or restoring force becomes more than weight of the jumper and then net force on the jumper directs upwards. At this point beat frequency becomes maximum.
Answer:
The given statement is "True".
Explanation:
- Industrial spying or espionage seems to be the surreptitious but sometimes unconstitutional method of trying to investigate competition in the market to gain a competitive advantage throughout the commercial enterprise.
- The investigation's goal may be a closely guarded secret including a patented product design or formulation, or growth strategy details.
