How far from source can light be seen if a 100W source radiates 600 nm light uniformly all directions and human eye can detect the light if 20 photons per sec enter dark eye with 7mm diameter pupil?
This is a complicated problem. But I can do it !Energy of single photon energy = (h) (c) / (wavelength) = (6.626 x 10-34 J-s) (299,792,458 m/s) / (600 x 10-9 m)= 3.3107 x 10-19 JouleThe eye requires 20 photons per sec = 6.6214 x 10-18 watt.The ratio of the required power to the power of the source is the ratio of the area of a 7mm circleto the area of the big sphere centered on the source.(6.6214 x 10-18) / (100) = (pi x 0.00352) / (4 pi R2)R2 = (100) (pi x 0.00352) / (4 pi x 6.6214 x 10-18)R = (5 x 0.0035) / (sqrt(6.6214) x 10-9)= 0.0068 x 109 = 6.8 x 106 meters= 6,800 km (4,225.8 miles)Wow !
Which is thicker a 5mm or 7mm pencil lead?
A 7mm pencil lead is thicker than a 5mm pencil lead. The diameter of the lead determines its thickness, so the lead with a larger diameter will be thicker.
Which is thicker a 7mm or 9mm pencil lead?
A 9mm pencil lead is thicker than a 7mm pencil lead.
Is 7mm larger than 5mm?
Yes, 7mm is larger than 5mm. The numerical value of 7 is greater than 5, indicating that 7mm is a larger measurement than 5mm. In terms of size and length, 7mm would be longer than 5mm.
What pen writes finer .5mm or .7mm?
.5mm is finer than .7 mm
Is a 7 mm mechanical pencil the same as a number 2 pencil?
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
What is the range of 2mm 2mm 5mm 7mm?
It is 7 mm - 2 mm = 5 mm.
Thickness of a pencil?
A Pencil has a thickness of about 7 milimeters (mm).
Could you draw a 7 millimeter line?
Yes. Its small obviously, but at just over half a centimetre, it is definitely a line!! =D Yes. Do you want a line 7mm in lenght or a line that is 7mm wide (many writing pens draw lines that are 5mm & 7mm wide).
What mm dive hood should you use?
Depend on the temperature of the water. >80F none 65-79F use 5mm <65 use 7mm
