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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
