ICSE Class 9: Measurement of Length Videos | Measurements and Experimentation

• what is the basic difference between the positive zero error and the negative zero error of the vernier scale then of the positive zero error and the negative zero error of the s crew gauge
• why it is said that if this main scale zero mark is going between the mark 0 and 1 of the vernier scale why is it said that it is in negative zero error and what is the difference between the positive error and the negative error
• describe in steps how would you see a verniar calipers to measure the length of a small rod
• with the help of a labelled diagram explain how is the negative zero error of a screw gauge determined also explain how such an error corrected
• Which type of error is Present in the screw gauge.
• How can the least count of a screw gauge be decreased?
• what is measurement
• The wavelength of light is 589nm. What is its wavelength in Å.
• Wht do you understand by least count of instrument?
• how dicovered screw gauage?
