What else can I help you with?
What is an example of indirect light?
Where light has bounced off a surface first, rather than coming direct from the source. For example, light coming from an object on a table such as an apple. There is no light in the apple, but light comes off it from a bulb or the sun.
Why Sundials can't be used at night?
Sundials require sunlight.
Does being an astronomer require you to work inside or outside?
These days its almost all inside - with computers.
Why are eyeglasses so important?
Glasses are important in many ways, they r important because it helps people seee more clearly, and people who have a weak eye, didnt hv glasses they would run into things. AND MAN WOULD THAT HURT!
The differences between an aircraft and a spacecraft?
Spacecraft lack wings & their engines don't require air to function.
As the magnification used in microscope increases is more or less illumination needed Explain your answer?
As the magnification used in a microscope increases, more illumination is typically needed. This is because higher magnification levels require more light to produce a clear and detailed image of the specimen. Insufficient illumination can result in a dim or blurry image at higher magnifications.
Does the kitchen or parking area require more foot candles of illumination?
The kitchen requires more illumination than the parking area.
What is specific illumination?
Specific illumination refers to the amount of light that falls on a specific area or object. It is measured in lux or foot-candles and is important for tasks that require detailed vision, such as reading or working on small objects. Different activities require different levels of specific illumination for optimal visibility.
Does the amount of light needed increase or decrease as it moves to higher magnifications with the microscope?
As the magnification increases on a microscope, the amount of light needed to properly view the specimen also increases. This is because higher magnifications require more light to maintain a clear and detailed image.
Light intensity switch in a microscope?
A light intensity switch in a microscope controls the brightness of the light source used to illuminate the specimen. By adjusting the intensity of the light, users can optimize the contrast and visibility of the specimen under observation. This feature is particularly useful when viewing transparent or delicate samples that require precise illumination.
Compare and contrast the farming techniques of farming in India?
From where do farmers obtain their inputs that they require?
Why would one require an MRI with contrast?
An MRI with contrast is a high-tech medical imaging test that can help your doctor diagnose many different types of diseases. One would require an MRI with contrast if one had a history of tumors, cancers or surgeries.
What are the benefits of using a 150w light bulb in comparison to lower wattage options?
Using a 150-watt light bulb provides brighter illumination compared to lower wattage options, making it ideal for larger spaces or areas that require more light. Additionally, the higher wattage can help improve visibility and clarity in tasks that require detailed focus. However, it is important to consider energy efficiency and potential heat output when using a higher wattage bulb.
Is peroxisome visible under 400X magnification?
No, peroxisomes are generally not visible under standard light microscopy at 400X magnification. They are too small and require higher magnifications and specific staining techniques to be visualized.
Why do coral reefs occur in shallow water?
Because the animals that build most of the reef require strong illumination from the sun, and that is only available near the surface.
Is a cat scan or an mri more accurate at detecting brain aneurysms?
A CT Scan can image an aneurysm without a contrast injection even though it does better with a contrast agent. An MRI will require an contrast agent or an MRI/MRA.
What are physicalproperties?
somthing you can feel, see and touch in contrast to chemical properties which require tests to obtain results
