AI Thread Summary
To convert a wavelength of 720 nanometers to meters, one must use the conversion factor that 1 meter equals 1 billion (10^9) nanometers. The correct conversion involves dividing the nanometer value by 1 billion, resulting in 720 nanometers being equal to 720 x 10^-9 meters, or 7.2 x 10^-7 meters. The initial confusion stemmed from incorrectly dividing by 1000 instead of using the proper exponent. Understanding that 1 nanometer equals 10^-9 meters is crucial for accurate conversions. Properly applying this knowledge ensures correct answers in similar problems.

Homework Statement



the wavelength of a laser is 720 nanometers. convert the wavelength to meters.

Homework Equations



i am not sure of an equation that will help me.

The Attempt at a Solution



this question was on a quiz i had recently and i got it wrong. i just divided by 1000 as a complete guess.
 
Physics news on Phys.org
1 meter = 10^9 nanometers I believe
 
thank you! as i think about it now my teacher did remind me that always add 10^9 after the wavelength.
 
Its 10^-9 I believe.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
