Given that,
Central maximum = 1 cm
Distance from the window shade to the wall =4 m
We know that,
The visible range of the sun light is 400 nm to 700 nm.
(a). We need to calculate the average wavelength
Using formula of average wavelength
Put the value into the formula
(b). We need to calculate the diameter of the pinhole
Using formula for diameter
Put the value into the formula
Hence, (a). The average wavelength 550 nm.
(b). The diameter of the pinhole is 0.537 mm.
The diver most likely refers to the ocean's surface when describing the squid's location. Option A is correct.
<h3>What is the height?</h3>
The vertical distance between the object's top and the bottom is defined as height. It is measured in centimeters, inches, meters, and other units.
The organism is shown as;
Seaweed = - 20 meters
Clownfish = - 23 meters
Squid = - 44 meters.
The given data is a reference from the surface of the ocean. The negative sign in the data shows that the given height is below the ocean surface.
The diver most likely uses the ocean surface as a reference point to describe the position of the squid.
Hence, option A is correct.

A region around a charged partical or object. Let me know if this works. Hope I could help you.
Answer: True
Explanation: Following are the properties that are used to identify minerals:
(1) Color
(2) Hardness
(3) Magnetism : It is the property of mineral to attract or repel with other magnetic materials.
(4) Luster : It is the property that shows the surface is reflecting light or not.
(5) Reactivity: Reactivity is also responsible to identify mineral. How the mineral is reacting with acids, bases etc helps to identify type of minerals.
Answer:They stop because jet streams follow boundaries between hot and cold air.
