Answer:
1 . rays should passs through correct center or points(i.e. optic center or focus)
2.your line representing rays should be straight and u should tell the nature of image
Explanation:
The frequency of electromagnetic wave is inversely proportional to the wavelength of the wave.
The speed of a wave is directly proportional to the wavelength of the wave.
v = fλ
where;
The frequency and wavelength of electromagnetic waves is related by the following equation as shown below;
Thus, we can conclude that the frequency of electromagnetic wave is inversely proportional to the wavelength of the wave.

B) 0.0228938 m3
C) 0.5457875 m3
D) 0.0457875 m3
Answer: C) 0.5457875
Explanation: Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
where,
= initial volume of gas =
= initial temperature of gas =
= final volume of gas = 0?
= final temperature of gas =
Thus the final volume is
Following directions in an experiment is crucial for accurately studying the effect of a variable, obtaining valid and repeatable results, and ensuring safety. It is integral to the scientific method, which involves making observations, forming a hypothesis, conducting an experiment, and analyzing results.
It's critical to follow all directions in an experiment correctly for several causes. First, experiments are a part of the scientific method, a process for investigating phenomena and acquiring new knowledge, or correcting and integrating existing knowledge. This method includes making observations, forming a hypothesis, conducting an experiment to test the hypothesis, and analyzing the results to reach a conclusion.
Second, correctly implementing the experimental procedure is necessary to measure the effect accurately and eliminate any lurking variables. It also involves control and experimental groups, which need to be treated differently only in the variable that's being tested. This way, any difference in results is attributed to that variable. Repeating the process under the same conditions confirms that your results were not accidental.
Finally, not following directions can lead to invalid results, incorrect conclusions, and even potential risks and hazards, particularly in certain fields such as chemistry or medicine. Therefore, meticulousness in adhering to instructions is essential for the reliability and safety of the experiment.
