Explanation:
It is given that,
Bandwidth of a laser source,
(b) Let t is the time separation of sections of sections of the light wave that can still interfere. The time period is given by :
(a) Let h is the coherence length of the source. It is given by :
c is the speed of light
l = 0.0099 m
Hence, this is the required solution.
I think that mechanism is called a <em>"lens turret"</em>.
Answer:Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation.
Explanation:
Answer:
0.203 micro meter
Explanation:
for destructive interference that appearsblack, use the formula
2 t = m λ / u (where m = 0 1 2 3 ... is order of minima)
where t = tickness,
u is the ref index = 1.32
Wavelenth λ = 535×10^-9 meter
for t (minimum) m = 1 (as m=0 is ruled out as t>0)
t = 1× 535×10^-9/2×1.32
t (min) = 202.65×10^-9 meter
OR
t (min) = 0.203×10^-6 meter = 0.203 micro meter
Answer:
it does not mirror the image
