How can you use indirect measurement to calulate the thickness of one index card?
You can use indirect measurement to calculate the thickness of one index card by stacking multiple index cards together and measuring the total thickness, then dividing that measurement by the number of cards in the stack. This will give you an approximation of the thickness of one index card based on the total thickness of the stack.
What is a millimeter closest to in thickness?
A millimeter is closest in thickness to the thickness of a credit card or the edge of a dime.
What unit is the thickness of paper and card measured in?
Paper thickness is measured in grams per square metre (gsm). This is the weight of one square metre of the paper.Answer 2g/m² (gsm) is not a measure of thickness, it is a measure of weight per unit area. Thickness is measured in micrometres (µm).
What is card thickness measured in?
Card thickness is typically measured in points or mils. One point is equal to 0.001 inches, while one mil is equal to 0.001 inches as well. Both measurements are commonly used to describe the thickness of cards, such as business cards or playing cards.
A thin layer of oil with index of refraction 1.28 is floating on water what is the minimum thickness of the oil in the region that reflects green light of wavelength 536 nm?
The minimum thickness of the oil film should be equal to half the wavelength of light in the oil medium (because of phase change upon reflection). The formula for minimum thickness is: t = λ / (2 * n), where t is the thickness, λ is the wavelength of light, and n is the refractive index of the medium. Plugging in the values, we get t = 536 nm / (2 * 1.28) ≈ 209.4 nm. So, the minimum thickness of the oil film should be approximately 209.4 nm.
