Answer:
Contrast, is the right answer.
Explanation:
The difference in color or luminance that makes an object separable is known as Contrast. In the context of the real-world visual perception, it is defined by the variance in the color and shine of the object and other articles within the corresponding area of view. Contrast sensitivity is one of the most significant measures of visual function, particularly in the situation of fog, glare or low light.
Aḥmad ibn Mājid ( أحمد بن ماجد), also known as the Lion of the Sea,[1] was an Arab navigator and cartographer born c. 1432[2] in Julfar, part of Oman under the Nabhani dynasty rule at the time,[3][4] (present-day Ras Al Khaimah, United Arab Emirates).[5] He was raised in a family famous for seafaring; at the age of 17 he was able to navigate ships. The exact date is not known, but ibn Majid probably died in 1500. Although long identified in the West as the navigator who helped Vasco da Gama find his way from Africa to India, contemporary research has shown Ibn Majid is unlikely even to have met da Gama.[6] Ibn Majid was the author of nearly forty works of poetry and prose.
