The sound

The Tools offer many possibilities for studying sound waves:

In addition to this, you need to know more about it.

1. the Frequency Generator allows you to generate pure tones on two phase-shiftable and volume-adjustable channels,

In addition to this, you need to know more about it.

2. the Sound library contains many examples of sounds that you can study with your students (tuning forks, musical instrument notes, white noise, Doppler effect, ...), such as:

Scale 440 hertz

Improvements on the synthesizer and new sounds in the sound library (tuning forks, white noise) for new experiences

Version 2.8.0

 

Added luminance. Using the camera to calculate the luminance.   The luminance is proportional to the light intensity but, unlike the illumination measurement, does not take into account the surface of the light source. It is the visual feeling of light intensity.

FizziQ calculates the relative luminance, i.e. the luminance compared to a reference. The luminance is calculated as the average of the red, green and blue components detected by the smartphone camera over the entire image and referred to the calibration value. Calibration is necessary because smartphones constantly adjust the image capture parameters so that the image is the best possible, Calibration allows you to fix the image acquisition parameters and therefore to be able to compare the luminance that you observe relative to the initial luminance.

Two types of luminance are calculated, the local luminance and the global luminance . Global Luminance calculates the average luminance of all pixels in the image captured by the camera. Local luminance calculates the value on the central pixels of the image. The measurement is updated at a frequency of approximately 10 Hz, available on iOS and Android.

Version 2.6.0

Addition of tables. User can create a table with two columns and multiple rows to enter values ​​just like he would on an Excel table. He can easily graph the data.

Version 2.5.0

Addition of the Colorimetry module (colors, spectrum and absorbance):

FizziQ uses the photographic detector present in smartphones to calculate various parameters that characterize the color reflected or transmitted by objects in the field of the camera.

The Color screen gives you a lot of information about the color of the center of the image: a sample of the color perceived by the sensor and its common name, the spectrum in% of the maximum value of the components red, green and blue that make up that color, the tint on the HSV scale, and the intensity of that tint.

The color spectrum gives the composition of the red, green and blue components of the camera's Bayer filter. This filter allows wavelengths around the 460 nm (blue), 550 nm (green) and 640 nm (red) wavelengths to pass.

Absorbance measures the decimal logarithm of the ratio between the reference light intensity determined during calibration and the transmitted light intensity.

Colorimetry measurements are updated at a frequency greater than 10 Hz, available on iOS and Android.
