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.
For an object to appear red what must the object do to red light waves?
For an object to appear red, it must absorb all other colors of light and reflect red light waves. The object's surface reflects only the red light waves, while absorbing all other colors. This selective reflection is what gives the object its red appearance.
For a sound wave to produce an echo it must?
To produce an echo, a sound wave must reflect off a surface and travel back to the listener's ears. This reflection can occur off various surfaces, such as walls, buildings, or mountains, depending on the environment. The time interval between the original sound and its reflection must be at least 0.1 seconds for a distinct echo to be perceived by the listener.
What must an object be for you to see it?
For an object to be seen, it must reflect light into your eyes. This reflection allows your brain to interpret the information and form an image of the object in your mind. The object must also be within your field of vision and not obstructed by other objects.
When light hits an object it is reflected a shiny object reflects more light then a dull object?
Yes, that's correct! Shiny objects have a smoother surface, so when light hits them, it reflects more directly and uniformly, resulting in a brighter reflection. Dull objects have a rougher surface, causing light to scatter in various directions, leading to a less intense reflection.

What 3 things must happen to be able to see something?
Light must be present to illuminate the object, the object must reflect or emit light, and the eyes must be able to detect and process the light entering them.
3 things that must happen before seeing an object?
You must have reflection upon you. For example a mirror is an object that can reflect on yourself.Most of the time when you see yourself in the mirror but not always. Mirrors can also show things from different directions as well. Mirrors are shiny surfaces that reflect off light. When you hold a mirror, it can show things behind you that you never thought was there.
What are the conditions for seeing the image of an object in a plane mirror?
To see the image of an object in a plane mirror, the object must be in front of the mirror, the observer must be able to see both the object and its mirrored image by looking directly at the mirror, and the observer and the object must be in the same line perpendicular to the mirror surface.
For what reasons might a designer need to know the volume and surface area of an object?
Designers must know the volume and surface area of an object because they must know how much space the object has inside it to put mabey parts in the object and to see how much the object weighs to see if it can fit somewhere without breaking it
What will an object always do when acted on by an unbalanced force?
There's no such thing as "an unbalanced force". But when the entire group of forceson an object is unbalanced, then the object must accelerate.
What happens to the vertical component of surface energy in Young's equation?
The vertical components of surface energy in Young's equation point in the same direction. They add up to balance the weight of the object. The weight must be lower than the surface tension can hold. The object must also not be wettable.
Which law tells you if a object will float or sink?
You must compare the densities of the object and whatever substance you are putting it in. If the density of an object is greater than the substance it is in, then the object will not float on the surface
