When rays fall on a diffraction grating normally (perpendicular to the surface), they spread out evenly across the grating, maximizing the interference pattern observed. This is because the angle of incidence affects how the waves interact with each slit on the grating, influencing the resulting diffraction pattern. Normal incidence ensures optimal alignment for constructive interference.

What must be true of the surface of an object for it to reflect an entire image?
For an object to reflect an entire image, its surface must be smooth and flat. Rough or curved surfaces will distort or scatter the reflection, preventing an entire image from being reflected.

it must be smooth
What properties must a surface have if the light that reflects from it forms a clear image?
A surface must be smooth, flat, and have a high level of reflectivity for light to form a clear image when it reflects off of it. Additionally, the surface should be free from distortions or imperfections that can scatter or blur the reflected light.
What criteria must be met in order for an object to be in free fall?
It's about as simple as it sounds. an object with no other force exerted on it but the force of gravity itself that is not in contact with a surface is in free fall. The only minor draw back you have is wind resistance. Everything would fall at the exact same velocity if not for variations in mass distributions and wind.=====================Answer #2:The definition of free fall is: NO other force acting on the object other than theforce of gravity. So if you're falling through air, you're not in free fall. Sky diversuse the term, and they're welcome to it, but technically, it's not really.
Is free fall balanced or unbalanced?
An object in free fall is accelerating, so the forces on it must be unbalanced.
What must occur before precipitation can fall on earths surface.?
Evaporation and condensation
What must occur before precipitation can fall to earth's surface?
Before precipitation can fall to Earth's surface, water vapor in the atmosphere must condense and form clouds. Once the clouds reach a point where they can no longer hold the condensed water, precipitation such as rain, snow, sleet, or hail will fall to the surface.
What kind of safety precautions should be used when installing fiberglass grating?
You must first read the instructions. While operating, you must also wear gloves and safety goggles.
Why must you not make the stairs of your house well-polished and shiny?
Because it would be very likely someone could slip on the polished surface and fall !

Why you must fall in love?

What must happen to surface tension in order to clean a surface?
Surface tension must be reduced in order to clean a surface effectively. This can be achieved by using a cleaning agent or detergent that helps to break the surface tension, allowing the cleaning solution to spread and penetrate the surface for thorough cleaning.
