A line graph is titled “Water Full-Range Spectral Absorption Curve.” The x-axis is titled “Wavelength” and the y-axis is titled “Absorption ( 1 per meter ).” Evenly spaced tick marks on the x-axis denote 10 nanometers, 100 nanometers, 1 micrometer, 10 micrometers, 100 micrometers, 1 millimeter, and 10 millimeters. Evenly spaced tick marks on the y-axis denote 10 superscript negative two, 10 superscript negative one, 10 superscript zero, 10 superscript one, 10 superscript two, 10 superscript three, 10 superscript four, 10 superscript five, 10 superscript six, 10 superscript seven, and 10 superscript eight. Above the graph, horizontal lines indicate the range of wavelengths for U V, V I S, near I R , mid I R , far I R , and E H F. The graph contains one line that begins at 10 nanometers and a little more than 10 superscript six. Moving from left to right, this line ascends gradually until it reaches a point near 100 nanometers and 10 superscript eight. From this point, the line steeply descends to a point a little more than halfway between 100 nanometers and 1 micrometer, and slightly more than 10 superscript two. This point indicates the end of the range labeled “U V” and the beginning of the range labeled “V I S.” The range labeled “V I S” is shaded with a color spectrum including the full range of Roy G Biv colors. Here, the line briefly descends in the same path as before, and then steeply ascends to a point near 1 micrometer and 10 superscript zero. This point indicates the end of the range labeled “V I S” and the beginning of the range labeled “near I R.” The line continues its steep ascent, with short, abrupt descents in between, until it reaches a point a little more than halfway between 1 micrometer and 10 micrometers, and a little more than 10 superscript six. This point indicates the end of the range labeled “near I R” and the beginning of the range labeled “mid I R.” Here, the line moves steeply and sporadically up and down until it reaches a point a little more than halfway between 10 micrometers and 100 micrometers, and slightly more than 10 superscript five. This point indicates the end of the range labeled “Mid I R” and the beginning of the range labeled “Far I R.” The line descends very gradually to a point slightly more than 1 millimeter and slightly more than 10 superscript four. This point indicates the end of the range labeled “Far I R” and the beginning of the range labeled “E H F.” The line continues its gradual descent to 10 millimeters and slightly more than 10 superscript three. This point indicates the end of the range labeled “E H F.”
Water full-range spectral absorption curve. This curve shows the full-range spectral absorption for water. The y -axis signifies the absorption in 1/cm. If we divide 1 by this value, we will obtain the length of the path (in cm) after which the intensity of a light beam passing through water decays by a factor of the base of the natural logarithm e (e = 2.718281828).

why is communication effective
Dakolo Reply
Communication is effective because it allows individuals to share ideas, thoughts, and information with others.
effective communication can lead to improved outcomes in various settings, including personal relationships, business environments, and educational settings. By communicating effectively, individuals can negotiate effectively, solve problems collaboratively, and work towards common goals.

Every time someone flushes a toilet in the apartment building, the person begins to jumb back automatically after hearing the flush, before the water temperature changes. Identify the types of learning, if it is classical conditioning identify the NS, UCS, CS and CR. If it is operant conditioning, identify the type of consequence positive reinforcement, negative reinforcement or punishment

Isn't practices worldwide, be it psychology, be it science. isn't much just a false belief of control over something the mind cannot truly comprehend?

explain how nature and nurture affect the development and later the productivity of an individual.
Amesalu Reply
nature is an hereditary factor while nurture is an environmental factor which constitute an individual personality. so if an individual's parent has a deviant behavior and was also brought up in an deviant environment, observation of the behavior and the inborn trait we make the individual deviant.

I am taking this course because I am hoping that I could somehow learn more about my chosen field of interest and due to the fact that being a PsyD really ignites my passion as an individual the more I hope to learn about developing and literally explore the complexity of my critical thinking skills

What are the treatment for autism?
Magret Reply
hello. autism is a umbrella term. autistic kids have different disorder overlapping. for example. a kid may show symptoms of ADHD and also learning disabilities. before treatment please make sure the kid doesn't have physical disabilities like hearing..vision..speech problem. sometimes these
Jharna
continue.. sometimes due to these physical problems..the diagnosis may be misdiagnosed. treatment for autism. well it depends on the severity. since autistic kids have problems in communicating and adopting to the environment.. it's best to expose the child in situations where the child
Jharna
child interact with other kids under doc supervision. play therapy. speech therapy. Engaging in different activities that activate most parts of the brain.. like drawing..painting. matching color board game. string and beads game. the more you interact with the child the more effective
Jharna
results you'll get.. please consult a therapist to know what suits best on your child. and last as a parent. I know sometimes it's overwhelming to guide a special kid. but trust the process and be strong and patient as a parent.
