Answer:
Option e. Blue/Violet
Explanation:
We know that when white light passes through a diffraction grating it spits into a band of seven colors or spectrum which includes the color in the order VIBGYOR that stands for Violet, Indigo, Blue, Green, Yellow, Orange and Red respectively.
Red light has the longest wavelength and is least scattered whereas Violet light with the shortest wavelength is the one to get most scattered and as we move far from bright spot at the center, there is an increase in the wavelength of light, thus the color that corresponds to the closest one is Violet with the shortest wavelength in the band.
Compressional wave! this is because you are compressing the spring coils together, thus creating a compressional wave!
Answer:
Explanation:
i. Accuracy in measurement is a term that is used to describe the closeness of a measured value to its actual value. It relates the actual value to the measured values.
Therefore in the given question, Amy's measurement of the salt's mass is accurate because her final value is close to all the measured values.
ii. Precision in measurement is a term that is used to describe the closeness of different measured values to each other. It relates the keenness in the measured values.
Thus, Amy's measurements of the salt's mass is precise because the values of the masses are close to one another.
